Move Elements to End

Write a Python program to move the specified number of elements to the end of the given list.

Use slice notation to get the two slices of the list and combine them before returning

Sample Solution:

Python Code:

# Define a function named 'move_end' that moves elements of a list by a given 'offset.'
def move_end(nums, offset):
    return nums[offset:] + nums[:offset]
    # Slices the list from the 'offset' position to the end and concatenates it with the portion from the start to the 'offset' position.

# Test the 'move_end' function with different lists and offsets.
print(move_end([1, 2, 3, 4, 5, 6, 7, 8], 3))
# Move the elements three positions to the end. (Expected output: [4, 5, 6, 7, 8, 1, 2, 3])

print(move_end([1, 2, 3, 4, 5, 6, 7, 8], -3))
# Move the elements three positions to the beginning. (Expected output: [6, 7, 8, 1, 2, 3, 4, 5])

print(move_end([1, 2, 3, 4, 5, 6, 7, 8], 8))
# The 'offset' equals the length of the list, resulting in the same list.

print(move_end([1, 2, 3, 4, 5, 6, 7, 8], -8))
# The negative 'offset' equals the negative length of the list, resulting in the same list.

print(move_end([1, 2, 3, 4, 5, 6, 7, 8], 7))
# Move the elements seven positions to the end. (Expected output: [2, 3, 4, 5, 6, 7, 8, 1])

print(move_end([1, 2, 3, 4, 5, 6, 7, 8], -7))
# Move the elements seven positions to the beginning. (Expected output: [8, 1, 2, 3, 4, 5, 6, 7])

Sample Output:

[4, 5, 6, 7, 8, 1, 2, 3]
[6, 7, 8, 1, 2, 3, 4, 5]
[1, 2, 3, 4, 5, 6, 7, 8]
[1, 2, 3, 4, 5, 6, 7, 8]
[8, 1, 2, 3, 4, 5, 6, 7]
[2, 3, 4, 5, 6, 7, 8, 1]
