Left, Right Shift

Create two functions: a left-shift function and a right-shift function. Each function will take in a list and a single parameter: the number of shifts.

[1, 2, 3, 4, 5]

[2, 3, 4, 5, 1]  # left shift of 1
[5, 1, 2, 3, 4]  # left shift of 4

[5, 1, 2, 3, 4]  # right shift of 1
[3, 4, 5, 1, 2]  # right shift of 3

Examples

left_shift([1, 2, 3, 4], 1) ➞ [2, 3, 4, 1]

right_shift([1, 2, 3, 4], 1) ➞ [4, 1, 2, 3]

left_shift([1, 2, 3, 4, 5], 3) ➞ [4, 5, 1, 2, 3]

left_shift([1, 2, 3, 4, 5], 5) ➞ [1, 2, 3, 4, 5]
# You have fully shifted the list, you end up back where you began.

left_shift([1, 2, 3, 4, 5], 6) ➞ [2, 3, 4, 5, 1]
# You should be able to take in numbers greater than the length.
# Think of the length of the list as a modulo.

Notes

• n might be higher than the number of values in the list.
• n will never be negative.
