Shift 2D Grid Lab
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 togrid[i][j + 1]
.  Element at
grid[i][n  1]
moves togrid[i + 1][0]
.  Element at
grid[m  1][n  1]
moves togrid[0][0]
.
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

Export the function
shiftGrid
from the fileindex.js
. Make sure this function takes in two arguments  thegrid
array and an integerk
, and returns a 2D grid after applying the shift operationk
times. 
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]].
