    189 - Rotate Array\. Medium 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?
