Rotate Array

EasyArrayString

🧠 Description

You are given an array of integers nums
You are also given an integer k
Your task is to rotate the array to the right by k steps

🔁 What does "rotate right" mean?

Each step moves elements one position to the right
The last element moves to the front

🧪 Example

Input:
```
nums = [1, 2, 3, 4, 5, 6, 7]
k = 3
```
Output:
```
[5, 6, 7, 1, 2, 3, 4]
```

⚙️ Requirements

You must modify the array in-place
Do not use extra space (O(1) space only)

📏 Constraints

1 ≤ nums.length ≤ 10⁵
-10⁹ ≤ nums[i] ≤ 10⁹
0 ≤ k ≤ 10⁹

Examples

Example 1

Input: [1, 2, 3, 4, 5, 6, 7], 3

Output: [5,6,7,1,2,3,4]

Example 2

Input: [1, 2], 0

Output: [1,2]

Example 3

Input: [1, 2, 3], 3

Output: [1,2,3]
