1260\. Shift 2D Grid

Easy

Given a 2D `grid` of size `m x n` and an integer `k`. You need to shift the `grid` `k` times.

In one shift operation:

*   Element at `grid[i][j]` moves to `grid[i][j + 1]`.
*   Element at `grid[i][n - 1]` moves to `grid[i + 1][0]`.
*   Element at `grid[m - 1][n - 1]` moves to `grid[0][0]`.

Return the _2D grid_ after applying shift operation `k` times.

**Example 1:**

![](https://assets.leetcode.com/uploads/2019/11/05/e1.png)

**Input:** `grid` = [[1,2,3],[4,5,6],[7,8,9]], k = 1

**Output:** [[9,1,2],[3,4,5],[6,7,8]]

**Example 2:**

![](https://assets.leetcode.com/uploads/2019/11/05/e2.png)

**Input:** `grid` = [[3,8,1,9],[19,7,2,5],[4,6,11,10],[12,0,21,13]], k = 4

**Output:** [[12,0,21,13],[3,8,1,9],[19,7,2,5],[4,6,11,10]]

**Example 3:**

**Input:** `grid` = [[1,2,3],[4,5,6],[7,8,9]], k = 9

**Output:** [[1,2,3],[4,5,6],[7,8,9]]

**Constraints:**

*   `m == grid.length`
*   `n == grid[i].length`
*   `1 <= m <= 50`
*   `1 <= n <= 50`
*   `-1000 <= grid[i][j] <= 1000`
*   `0 <= k <= 100`
