Hi, here's your problem today. This problem was recently asked by Facebook:
Given an array and an integer k, rotate the array by k spaces. Do this without generating a new array and without using extra space.
Here's an example and some starter code
def rotate_list(nums, k): # Fill this in. a = [1, 2, 3, 4, 5] rotate_list(a, 2) print(a) # [3, 4, 5, 1, 2]
