<jupyter_start><jupyter_text>Given an array, rotate the array to the right by k steps, where k is non-negative.Follow up:Try to come up as many solutions as you can, there are at least 3 different ways to solve this problem.Could you do it in-place with O(1) extra space?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 <= 2 * 104-231 <= nums[i] <= 231 - 10 <= k <= 105<jupyter_code>def rotate(a, k):
    
    return a[-k:] + a[:-k]
