    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:

    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
