Given an array, rotate the array to the right by k steps, where k is non-negative.
"""
Example 1:
Input: nums = [1, 2, 3, 4, 5, 6, 7], k = 3
Output: [5, 6, 7, 1, 2, 3, 4]
Explanation:
rotate 1 steps to the right: [7, 1, 2, 3, 4, 5, 6]
rotate 2 steps to the right: [6, 7, 1, 2, 3, 4, 5]
rotate 3 steps to the right: [5, 6, 7, 1, 2, 3, 4]
Example 2:
Input: nums = [-1, -100, 3, 99], k = 2
Output: [3, 99, -1, -100]
Explanation:
rotate 1 steps to the right: [99, -1, -100, 3]
rotate 2 steps to the right: [3, 99, -1, -100]
Constraints:
1 <= nums.length <= 105
-231 <= nums[i] <= 231 - 1
0 <= k <= 105
Follow up:
Try to come up with as many solutions as you can. There are at least three different ways to solve this problem.
Could you do it in -place with O(1) extra space?

Do not return anything, modify nums in-place instead.

for i in range(0, k):
x = nums[len(nums)-1]
nums.pop()
nums.insert(0, x)
