## Question

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 = 3Output:[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 = 2Output:[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}

**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?

## Python Solution

class Solution: def rotate(self, nums: List[int], k: int) -> None: n = len(nums) k = k % n nums[:] = nums[n-k:] + nums[:n-k]
