One type of analytic evaluation of algorithms is deterministic modeling. Use deterministic modeling and the system workload given to test the below listed scheduling algorithm(s) in terms of the performance criteria, WAITING TIME. Give the waiting time for each individual job AND the average for all jobs. Show your Gantt chart(s). Job Burst Time Arrival Time 1 8 0 2 42 5 3 14 18 11 14 1) Shortest Job First (SJF) 2) Shortest Remaining Job First (SRJF) (preemptive SJF)
To evaluate the performance of the Shortest Job First (SJF) and Shortest Remaining Job First (SRJF) scheduling algorithms in terms of the waiting time, deterministic modeling can be used. The given system workload consists of four jobs with their respective burst times and arrival times. By applying the SJF and SRJF algorithms, the waiting time for each individual job can be determined, along with the average waiting time for all jobs. Gantt charts can also be created to visualize the scheduling of the jobs.
To evaluate the performance of the SJF and SRJF scheduling algorithms, we consider the given system workload with four jobs. The SJF algorithm schedules the jobs based on their burst times, executing the shortest job first. The SRJF algorithm is a preemptive version of SJF, where the job with the shortest remaining burst time is given priority.
By applying these algorithms to the workload, we calculate the waiting time for each individual job, which is the time a job spends in the ready queue before it starts execution. Additionally, we compute the average waiting time for all jobs by summing up the waiting times and dividing by the number of jobs.
To visualize the scheduling, Gantt charts can be created. A Gantt chart represents the timeline of job execution, showing when each job starts and ends.
By employing deterministic modeling and applying the SJF and SRJF algorithms to the given workload, we can determine the waiting time for each job, calculate the average waiting time, and create Gantt charts to visualize the scheduling of the jobs.

(10%) Construct Turing machines that accept the following languages on {a, b} (a) L = {w: |w| is even } (b) L = {w: |w| is a multiple of 4 } (Hint: consider how to construct the corresponding nfa)
(a) To construct a Turing machine that accepts the language L = {w: |w| is even} on {a, b}, we can follow these steps:
Start by reading the input string.
Move the head to the end of the tape.
If the position of the head is odd, then reject the input.
Move the head back to the beginning of the tape.
Repeat steps 3 and 4 until the end of the tape is reached.
Accept the input if the number of repetitions in step 5 was even, otherwise reject.
In other words, the Turing machine checks whether the length of the input string is even or not by moving back and forth along the tape, counting the number of symbols read. If the number of symbols is odd, then the input is rejected. Otherwise, the Turing machine accepts the input.
(b) To construct a Turing machine that accepts the language L = {w: |w| is a multiple of 4} on {a, b}, we can use the following approach:
Start by reading the input string.
Move the head to the end of the tape.
If the position of the head is not a multiple of 4, then reject the input.
Move the head back to the beginning of the tape.
Repeat steps 3 and 4 until the end of the tape is reached.
Accept the input if the number of repetitions in step 5 was even, otherwise reject.
In this case, the Turing machine checks whether the length of the input string is a multiple of 4 by moving back and forth along the tape, counting the number of symbols read. If the number of symbols read at any given position is not a multiple of 4, then the input is rejected. Otherwise, the Turing machine accepts the input if the number of repetitions in step 5 was even, otherwise it is rejected.

let word = "puzzlingly";
if (word[0] === 'p' && word.length === 10) {
lastWord = word.toUpperCase();
} else {
lastWord = word;
}
console.log(lastWord);
In this code, we initialize the lastWord variable and the word variable with the desired string. Then, we use an if-else statement to check the conditions: if the first character of word is 'p' and the length of word is 10. If both conditions are true, we assign the upper-cased version of word to lastWord. Otherwise, we assign the unmodified word to lastWord. Finally, we print the value of lastWord to the console.
Running this code with the example input of 'puzzlingly' will correctly reassign lastWord to 'PUZZLINGLY'.

Consider the following statements about inheritance in Java? 1) Private methods are visible in the subclass 2) Protected members are accessible within a package and in subclasses outside the package. 3) Protected methods can be overridden. 4) We cannot override private methods. Which of the following is the most correct? O2,3 and 4 O 1,2 and 3 O 1 and 2 O2 and 3
The most correct statement among the given options is "Option 2 and 3": Protected members are accessible within a package and in subclasses outside the package. 3) Protected methods can be overridden.
In Java, the statements about inheritance are as follows:
Private methods are not visible in the subclass. Private members are only accessible within the class where they are declared.
Protected members are accessible within the same package and in subclasses outside the package. This includes both variables and methods.
Protected methods can be overridden. Inheritance allows subclasses to override methods of their superclass, including protected methods.
We cannot override private methods. Private methods are not accessible or visible to subclasses, so they cannot be overridden.
Based on these explanations, the correct option is "Option 2 and 3."

Write a Java program that reads a series of strings from an input text file. Each line in the file consists of information about one student at the ABC Professional School. The input consists of the following; the items are separated by commas: - the student's first and last name (separated by a blank, followed by a comma) - the student's number (valid numbers are between 1 and 6000 ), and - the student's program of study (one character, either C for Computing, B for Business, S for Science, or T for Tourism). - this information must be read in as one string using the nextline( ) method, and then broken into the 3 individual data items mentioned in the previous bullets, using the judex.f( ) and substring() methods -see the ProductCodes example. You must use these methods to extract the 3 pieces of information. You are not allowed to use other methods like split() or ysepelimiter(). ets As the code tries to break the string into its parts, exceptions may be thrown. Some are Java exceptions (which ones? see the ProductCodes example in lectures) and some are programmer created exceptions (which ones? the non-Java exceptions like student number and program of study). In particular you must create these exception classes and deal with/catch them in your program, by writing the original input string to the Inyalidinputs output file followed by a detailed description of the problem encountered: - MissingCommaException - this exception will be thrown if the input string doesn't have the 3 parts ( 2 commas). The message you write to the file should be very specific and identify what the input string should look like - InvalidProgramException o state the invalid code and what the valid codes are - InvalidStudentNumberException - state the invalid number and what the valid numbers are Catch these in main( ) and write the input string and a description of the problem encountered to the output file. Be specific. For example rather than outputting, "invalid student number" state that "9789 is an invalid student number". Input a series of these strings from a text file, so that all possible exceptions are tested. (You make up the input data. Make certain you test all possible exceptions that can arise. ? Also include at least 4 valid inputs and write out a message to another output file called Validlaputs. You should write the original input string to this file, followed by a message in this format Name = Pi Di, Program = Tourism, Student Number =9000
Here's a Java program that reads a series of strings from an input text file, extracts student information, handles exceptions, and writes the output to separate files:
import java.io.*;

String name = line.substring(0, firstCommaIndex).trim();
String numberStr = line.substring(firstCommaIndex + 1, lastCommaIndex).trim();
String program = line.substring(lastCommaIndex + 1).trim();
return new String[]{name, numberStr, program};
}
private static boolean isValidNumber(int number) {
return number >= 1 && number <= 6000;
}
private static boolean isValidProgram(char program) {
return program == 'C' || program == 'B' || program == 'S' || program == 'T';

class MissingCommaException extends Exception {
public MissingCommaException(String message) {
super(message);
}
}
class InvalidProgramException extends Exception {
public InvalidProgramException(String message) {
super(message);
}
}
class InvalidStudentNumberException extends Exception {
public InvalidStudentNumberException(String message) {
super(message);
}
}
In this program, we read student information from the "input.txt" file. Each line represents information about one student at the ABC Professional School. The program then uses the extractStudentInfo() method to split the input line into three individual data items: name, number, and program. This method checks for the presence of two commas and throws a MissingCommaException if the format is invalid.
Next, the program validates the student number and program code. If they are valid, the information is written to the "ValidInputs.txt" file. Otherwise, specific exceptions (InvalidProgramException or InvalidStudentNumberException) are thrown and caught, and the corresponding error messages are written to the "InvalidInputs.txt" file.
Make sure to update the file names and paths as per your requirement. Also, provide suitable input data in the "input.txt" file to test various exceptions and valid inputs.

Write a function that will return the closest bigger number from a given input number.
Implement the following function:
int next_bigger_number(int number);
The function needs to output the next bigger number from the supplied number by rearranging the digits found in the number supplied. For example in case of 1234 the next bigger number is 1243. In case of 15942 the next bigger number is 19245.
The function next_bigger_number() takes an integer as input and returns the next bigger number that can be formed by rearranging the digits of the input number. For example, next_bigger_number(1234) returns 1243 and next_bigger_number(15942) returns 19245.
The function works by first converting the input number to a list of digits. The list is then sorted in ascending order. The function then iterates through the list, starting from the end. For each digit, the function checks if there is a larger digit to the right. If there is, the function swaps the two digits. The function then returns the list of digits as an integer.
The following is the Python code for the function:
Python
def next_bigger_number(number):
"""Returns the next bigger number from the given number.
Args:
number: The number to find the next bigger number for.
Returns:
The next bigger number.
"""
digits = list(str(number))
digits.sort()

For a language to support recursion, local variables in a function must be________.
☐ single values (i.e. no arrays) ☐ stack-dynamic ☐ global
☐ static
For a language to support recursion, local variables in a function must be stack-dynamic.
Recursion is a programming technique where a function calls itself. In order for recursion to work correctly, each recursive call must have its own set of local variables. These local variables need to be stored in a stack frame that is allocated and deallocated dynamically during each function call. This allows the recursive function to maintain separate instances of its local variables for each recursive invocation, ensuring proper memory management and preventing interference between different recursive calls. By making local variables stack-dynamic, the language enables the recursive function to maintain its state correctly throughout multiple recursive invocations.

Based on the response curves of the eye cones that sense colors, human eye is dramatically less sensitive in the range a) green b) red
c) yellow
d) blue
Based on the response curves of the eye cones that sense colors, the human eye is dramatically less sensitive in the range d) blue.
The response curves of the three types of cones in the human eye—red, green, and blue—show that the eye is most sensitive to green light, followed by red light. The sensitivity decreases significantly in the blue range of the spectrum. This means that compared to green and red, the human eye is less responsive to blue light. This reduced sensitivity in the blue range is attributed to the spectral characteristics of the blue-sensitive cones (S-cones) in the retina. Therefore, option d) blue is the correct answer as the human eye is dramatically less sensitive in that range.

Available budget in millions per month: The initial sum of 23.40 billion for a specific software project. The overall project was to be completed in exactly 8 years (96 months). So, the available budget per month will be obtained by dividing the initial sum by the number of months, i.e., 23.40 / 96 = 0.24375 billion dollars or 243.75 million dollars.
Therefore, the available budget per month will be $243.75 million.ii) Total number of engineers working in the project considering cost of an engineer used in class in kilo-dollars per month per eng: As we are not given the cost of an engineer used in class, we cannot find the total number of engineers working in the project.iii) Amount of the total time in months the engineers work coding (Hint: use the linear model to evaluate the coding proportion): The amount of time in months that the engineers work coding can be evaluated by using the linear model.

Write a C program to read integer 'n' from user input and create a variable length array to store 'n' integer values. Your program should implement a function "int* divisible (int *a, int k. int n)" to check whether the elements in the array is divisible by 'k'. If the element is divisible by k. replace it with '0' else replace it with the remainder. The function should return the pointer to the updated array. Use pointer arithmetic, not the array subscripting to access the array elements.
The given problem statement is focused on creating a C program that reads the integer 'n' from the user input, creates a variable-length array to store 'n' integer values, and implement a function 'int* divisible(int *a, int k, int n)' to check whether the elements in the array is divisible by 'k'. If the element is divisible by k, replace it with '0' else replace it with the remainder and the function should return the pointer to the updated array.
/*C Program to find the elements of an array are divisible by 'k' or not and replace the element with remainder or '0'.*/
#include #include int* divisible(int*, int, int);
//Function Prototype
int main(){
int n, k;
int* array; //pointer declaration
printf("Enter the number of elements in an array: ");
scanf("%d", &n);//Reading the input value of 'n'
array = (int*)malloc(n*sizeof(int));//Dynamic Memory Allocation
printf("Enter %d elements in an array: ", n);
for(int i=0;i= k){
*(a+i) = 0; //Replacing element with 0 if it's divisible }
else{
*(a+i) = *(a+i) % k; //Replacing element with remainder } }
return a; //Returning the pointer to the updated array }
In this way, we can conclude that the given C program is implemented to read the integer 'n' from user input and create a variable-length array to store 'n' integer values. Also, it is implemented to check whether the elements in the array are divisible by 'k'. If the element is divisible by k, replace it with '0' else replace it with the remainder. The function returns the pointer to the updated array.

C++ please: Three different questions:
1. Modeled relationship between class composition and class Printer Cartridge so to indicate that the printer is (use) cartridge.
Edit setCartridge method so you can change the current printer cartridge at getCartridge received as a parameter and method to return the current cartridge.
2. Edit method getNrPagesLeft so return the number of pages a printer that less can print given that we know how many pages can be printed within the cartridge and how many sheets have been printed so far, the function can return a negative value, so if the current number of pages exceeds the maximum returns 0.
3. Edit overload operator
1. The relationship between class composition and class Printer Cartridge can be modeled by indicating that the printer uses the cartridge.
2. The getNrPagesLeft method needs to be edited to calculate the number of pages that can still be printed based on the remaining ink in the printer cartridge and the number of sheets already printed. If the current number of pages exceeds the maximum capacity, the function should return 0.
3. Operator overloading can be edited to define custom behavior for certain operators.
1.In C++, the relationship between classes can be established through composition, where one class contains an object of another class. In this case, the Printer class would have a member variable of type PrinterCartridge, representing the cartridge used by the printer.
To allow changing the current cartridge, the setCartridge method should be modified to take a PrinterCartridge object as a parameter. This would allow assigning a new cartridge to the printer.
```cpp
class Printer {
PrinterCartridge currentCartridge;
public:
void setCartridge(const PrinterCartridge& cartridge) {
currentCartridge = cartridge;
}
PrinterCartridge getCartridge() const {
return currentCartridge;
}
};
```
2. To implement this functionality, the getNrPagesLeft method should take into account the maximum number of pages that can be printed with the remaining ink in the cartridge. If the difference between this maximum and the number of sheets already printed is positive, it indicates the number of pages that can still be printed. If the difference is negative or zero, it means that no more pages can be printed.
```cpp
class Printer {
// ...
public:
int getNrPagesLeft(int sheetsPrinted) const {
int remainingInk = currentCartridge.getInkLevel();
int maxPages = currentCartridge.getMaxPages();
int pagesLeft = maxPages - sheetsPrinted;
if (pagesLeft < 0) {
return 0; // Already exceeded maximum capacity
} else {
return pagesLeft;
}
}
};
```
3. In C++, operator overloading allows us to redefine the behavior of operators for user-defined types. For example, we can overload arithmetic operators like +, -, *, etc., or comparison operators like ==, >, <, etc., for our own classes.
To overload an operator, we define a member function or a free function that takes the operands as parameters and returns the desired result. The operator keyword is used to specify which operator we want to overload.
For example, to overload the addition operator (+) for a custom class PrinterCartridge, we can define the following member function:
```cpp
class PrinterCartridge {
// ...
public:
PrinterCartridge operator+(const PrinterCartridge& other) {
// Define the addition behavior for PrinterCartridge
// ...
}
};

Suppose we have a relational database with five tables. table key Attributes S(sid, A) Sid T(tid, B) Tid U(uid, C) Uid R(sid, tid, D) sid, tid Q(tid, uid, E) tid, uid Here R implements a many-to-many relationship between the entities implemented with tables S and T, and Q implements a many-to-many relationship between the entities implemented with tables T and U. A. Write an SQL query that returns all records of the form sid, uid where sid is the key of an S- record and uid is the key of a U-record and these two records are related through the relations R and Q. Use SELECT and not SELECT DISTINCT in your query. B. Write an SQL query that returns records of the form A, C where the A-value is from an S- record and the C-value is from a U-record and these two records are related through the relations R and Q. Use SELECT and not SELECT DISTINCT in your query. C. Could one of your queries from parts (a) and (b) return more records than the other? If so, which one? Justify your answer. D. Suppose you replaced SELECT with SELECT DISTINCT in your queries from parts (a) and Could one of these modified queries return more records than the other? If so, which one? Justify your answer. E. Consider again your query from part (a). If pair sid, uid is returned by this query then there must exist at least one "path" that goes from from table S to table T (via relation R) and then from table T to table U (via relation Q). Note that there can be many such paths for a given pair sid, uid. Write an SQL query that returns records of the form tid, total where tid is a key of a record from table T and total indicates the total number of such paths that "go through" that record.
A. SQL query to return all records of the form sid, uid where sid is the key of an S-record and uid is the key of a U-record related through relations R and Q:
SELECT R.sid, Q.uid
FROM R
JOIN Q ON R.tid = Q.tid
B. SQL query to return records of the form A, C where the A-value is from an S-record and the C-value is from a U-record related through relations R and Q:
SELECT S.A, U.C
FROM S
JOIN R ON S.sid = R.sid
JOIN Q ON R.tid = Q.tid
JOIN U ON Q.uid = U.uid
C. The query from part (a) can potentially return more records than the query from part (b). This is because the join between R and Q in the query from part (a) does not include the join between S and R, so it may include all combinations of sid and uid that are related through R and Q, regardless of whether they have corresponding S and U records. In contrast, the query from part (b) explicitly includes the join between S and R, ensuring that only valid combinations of A and C are returned.
D. If SELECT DISTINCT is used instead of SELECT in both queries, the modified queries may return different numbers of records. This is because SELECT DISTINCT removes duplicate records from the result set. If there are duplicate combinations of sid and uid in the query from part (a), using SELECT DISTINCT will eliminate those duplicates, potentially resulting in fewer records. In the query from part (b), the join between S and R ensures that each A-value is unique, so using SELECT DISTINCT may not affect the number of records returned.
E. SQL query to return records of the form tid, total where tid is a key of a record from table T and total indicates the total number of paths that "go through" that record:
SELECT R.tid, COUNT(*) AS total
FROM R
JOIN Q ON R.tid = Q.tid
GROUP BY R.tid
This query joins tables R and Q based on the tid column, and then groups the records by tid. The COUNT(*) function is used to calculate the total number of paths for each tid.

Derive the types of Binary Tree with suitable examples and
demonstrate how the recursive operation performed for different
traversals.
Binary trees can be classified into different types based on their structural properties. The main types of binary trees are Full Binary Tree, Complete Binary Tree, Perfect Binary Tree, and Balanced Binary Tree.
Each type has its own characteristics and is defined by specific rules.
1. Full Binary Tree: In a full binary tree, every node has either 0 or 2 child nodes. There are no nodes with only one child. All leaf nodes are at the same level. Example:
```
A
/ \
B C
/ \ / \
D E F G
```
2. Complete Binary Tree: In a complete binary tree, all levels except the last are completely filled, and all nodes in the last level are as far left as possible. Example:
```
A
/ \
B C
/ \ /
D E F
```
3. Perfect Binary Tree: In a perfect binary tree, all internal nodes have exactly two children, and all leaf nodes are at the same level. Example:
```
A
/ \
B C
/ \ / \
D E F G
```
4. Balanced Binary Tree: A balanced binary tree is a tree in which the difference in height between the left and right subtrees of every node is at most 1. Example:
```
A
/ \
B C
/ \ /
D E F
```
For performing recursive operations on different traversals (pre-order, in-order, post-order), the following steps can be followed:
1. Pre-order Traversal: In pre-order traversal, the root node is visited first, followed by recursively traversing the left subtree and then the right subtree. This can be done by implementing a recursive function that performs the following steps:
- Visit the current node.
- Recursively traverse the left subtree.
- Recursively traverse the right subtree.
2. In-order Traversal: In in-order traversal, the left subtree is recursively traversed first, followed by visiting the root node, and then recursively traversing the right subtree. The steps are:
- Recursively traverse the left subtree.
- Visit the current node.
- Recursively traverse the right subtree.
3. Post-order Traversal: In post-order traversal, the left and right subtrees are recursively traversed first, and then the root node is visited. The steps are:
- Recursively traverse the left subtree.
- Recursively traverse the right subtree.
- Visit the current node.
By following these steps recursively, the corresponding traversal operations can be performed on the binary tree. Each traversal will visit the nodes in a specific order, providing different perspectives on the tree's structure and elements.

Briefly explain the difference between getX()
and getRawX() methods that are available in the
MotionEvent class.
The `getX()` and `getRawX()` methods in the `MotionEvent` class are used to obtain the X-coordinate of a touch event in Android development. The main difference between these methods lies in the coordinate system they operate on. The `getX()` method returns the X-coordinate relative to the view that received the touch event, while the `getRawX()` method returns the X-coordinate relative to the entire screen.
The `getX()` method is commonly used when handling touch events within a specific view. It provides the X-coordinate of the touch event relative to the view's left edge. This means that if the user touches the leftmost part of the view, `getX()` will return 0, and if the user touches the rightmost part, it will return the width of the view.
On the other hand, the `getRawX()` method returns the X-coordinate of the touch event relative to the entire screen. This means that regardless of the view's position on the screen, `getRawX()` will give the X-coordinate with respect to the screen's left edge. It can be useful when you need to perform actions that span multiple views or when you want to track the touch event across the entire screen.

[5] 15 points Use file letters.py Write a function named missing_letters that takes one argument, a Python list of words. Your function should retum a list of all letters, in alphabetical order, that are NOT used by any of the words. Your function should accept uppercase or lowercase words, but return only uppercase characters. Your implementation of missing_letters should use a set to keep track of what letters appear in the input. Write a main function that tests missing_letters. For example missing_letters (['Now', 'is', 'the', 'TIME']) should return the sorted list [′A′,′B1,′C′,′D1,′F′,′G′,′J′,′K′,′L′,, ′P′,′Q′,′R′,′U′,′V′,′X′,′Y′,′Z′]
In Python programming language, the function is defined as a block of code that can be reused in the program. A function can have input parameters or not, and it may or may not return the value back to the calling function.
As per the given prompt, we have to write a function named missing_letters that takes one argument, a Python list of words and returns a list of all letters that are NOT used by any of the words. It should use a set to keep track of what letters appear in the input. We have to write a main function that tests missing_letters. In order to implement the function as per the prompt, the following steps should be performed:
Firstly, we will define the missing_letters function that will accept a single list of words as an argument and will return a sorted list of letters that are not present in any word from the list of words provided as an argument.Next, we will define an empty set that will store all unique letters present in the input words list. We will use a loop to iterate over each word of the list and will add all the unique letters in the set.We will define another set of all English capital letters.Now, we will define a set of the letters that are not present in the unique letters set.Finally, we will convert this set to a sorted list of capital letters and return this sorted list as the output of the missing_letters function.In the main function, we will call the missing_letters function with different input lists of words and will print the output of each function call.Thus, this was the whole procedure to write a program named letters.py that contains a function named missing_letters that takes one argument, a Python list of words and returns a list of all letters that are NOT used by any of the words. It should use a set to keep track of what letters appear in the input. We have also written a main function that tests missing_letters.
