20.0% Acceptance

In this lab, you will be implementing a function that shifts a 2D grid for a given number of times. You are provided with a 2D grid of size `m x n` and an integer `k`. Your task is to shift the grid by `k` times.

During a single shift operation:

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

Your function should return the 2D grid after applying the shift operation `k` times.

## Example

### Example 1

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

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`

## Challenges

1. Export the function `shiftGrid` from the file `index.js`. Make sure this function takes in two arguments - the `grid` array and an integer `k`, and returns a 2D grid after applying the shift operation `k` times.

2. Test your function with the following case: `grid` = [[1,2,3],[4,5,6],[7,8,9]], `k` = 1. The expected output is: [[9,1,2],[3,4,5],[6,7,8]].
