1914. Cyclically Rotating a Grid
https://leetcode.com/problems/cyclically-rotating-a-grid
Description
You are given an m x n
integer matrix grid
, where m
and n
are both even integers, and an integer k
.
The matrix is composed of several layers, which is shown in the below image, where each color is its own layer:

A cyclic rotation of the matrix is done by cyclically rotating each layer in the matrix. To cyclically rotate a layer once, each element in the layer will take the place of the adjacent element in the counter-clockwise direction. An example rotation is shown below:
Return the matrix after applying
k
cyclic rotations to it.
Example 1:

**Input:** grid = [[40,10],[30,20]], k = 1
**Output:** [[10,20],[40,30]]
**Explanation:** The figures above represent the grid at every state.
Example 2:
**Input:** grid = [[1,2,3,4],[5,6,7,8],[9,10,11,12],[13,14,15,16]], k = 2
**Output:** [[3,4,8,12],[2,11,10,16],[1,7,6,15],[5,9,13,14]]
**Explanation:** The figures above represent the grid at every state.
Constraints:
m == grid.length
n == grid[i].length
2 <= m, n <= 50
Both
m
andn
are even integers.1 <= grid[i][j] <=5000
1 <= k <= 109
