-/**
- * 1260. Shift 2D Grid
- *
- * 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] becomes at grid[i][j + 1].
- * Element at grid[i][n - 1] becomes at grid[i + 1][0].
- * Element at grid[n - 1][n - 1] becomes at 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
