Given int[] array, return a new int[] that contains every other element of array. for example, if array = {0, 1, 2, 3, 4, 5}, return {0, 2, 4}.
Hint: How big does the new array have to be?
Tip: Write down an example array to help find the pattern between the index from the old array and the index in the new array.
This is how you do it in python:
Code:
def everyother(array):
return array[::2]
example_array = [0, 1, 2, 3, 4, 5]
print(everyother(example_array))
Output:
[0, 2, 4]
Explenation:
The key to this problem is "array[::2]".
Array[start : stop : step]
Writing "array[::2]" is the same as writing:
Array[0 : -1 : 2] or Begin at 0, stop at the end and take every 2:nd value

if command == 'Exit': # If the player enters "exit", the game should move them to the "exit" room.
print('You have eradicated the Virus.')
Answer:
Something like this?
The only requirement this doesn't exactly hit is moving the user to the "exit" room. It doesn't make use of that entry in the dictionary. However, this is the best way of doing it to avoid multiple "if" statements.

Write a function that receives a one-dimensional array of integers and returns a Python tuple with two values - the minimum and maximum values of the input array. The content of the input array must not be changed. You may assume that the input array will contain only integers, and will have at least one element. You do not need to check for these conditions. For full credit, the function must be implemented with O(N) complexity.
The function that receives array of integers and returns the minimum and maximum values as a tuple is as follows:
def min_max(array):
x = min(array)
y = max(array)
return (x, y)
print(min_max([4, 6, 7, 8, 1, 8, 14]))
Code explanationThe code is written in python.
We defined a function named "min_max". The function accepts a parameter called array.The variable x is used to store the minimum value of the array.The y variable is used to store the maximum value of the array.Then, we return the minimum and maximum values as a tuple.Finally, we call the function with the required parameter.learn more on python here: https://brainly.com/question/13199913

How do I find enchants faster on deepwoken?
Answer:
Rogue Constructs, Primadon, Fishing
Explanation:
Multiple methods may aid you in finding enchants faster. Notable ways include farming the Rogue Construct at Minityrsa which nets solid total loot (each item is rolled individually for enchants which is why larger chests usually means more enchants and why enchants can be in groups of more than 1 in chests) and farming Primadon. Fishing has also become a prominent method of enchant farming but is less reliable than the other two stated methods if you already have a strong PVE build. Happy enchant farming.

Which line of code moves the ball up?
1. myBall.pos.z = myBall.pos.z + 2
2. myBall.pos.x = myBall.pos.x + 1
3. myBall.pos = myBall.pos + 1
4. myBall.pos.y = myBall.pos.y + 2
The line of code that moves the ball up is myBall.pos.y = myBall.pos.y + 2. The correct option is 4.
What is code?The term "code" typically refers to a set of instructions written in a programming language and executable by a computer or interpreter to perform a specific task or set of tasks.
Code can be used to create software, websites, games, scripts, and other things. Python, Java, C++, JavaScript, and Ruby are among the programming languages that can be used to create it.
The line of code myBall.pos.y = myBall.pos.y + 2 is assigning a new value to the y-coordinate of the position vector myBall.pos of the object named myBall.
The new value of the y-coordinate is calculated by taking the current value of myBall.pos.y and adding 2 to it. The result is then assigned back to myBall.pos.y, effectively updating the position of the myBall object.
Thus, the correct option is 4.
