::::warning
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?
::::

### 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 <= 10^5`
- `-2^31 <= nums[i] <= 2^31 - 1`
- `0 <= k <= 10^5`

## Solution

```js
/**
 * @param {number[]} nums
 * @param {number} k
 * @return {void} Do not return anything, modify nums in-place instead.
 */
var rotate = function(nums, k) {
    
};
```
