Rotate Array

Given an integer array `nums`, rotate the array to the right by `k` steps, where `k` is non-negative. > **Note for this platform:** The method returns the modified `nums` array for testability. **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] ```
