You are given a 2D matrix of dimension and a positive integer . You have to rotate the matrix times and print the resultant matrix. Rotation should be in anti-clockwise direction.
Rotation of a matrix is represented by the following figure. Note that in one rotation, you have to shift elements by one step only.
It is guaranteed that the minimum of m and n will be even.
As an example rotate the Start matrix by 2:
Start First Second
1 2 3 4 2 3 4 5 3 4 5 6
12 1 2 5 -> 1 2 3 6 -> 2 3 4 7
11 4 3 6 12 1 4 7 1 2 1 8
10 9 8 7 11 10 9 8 12 11 10 9
Function Description
Complete the matrixRotation function in the editor below.
matrixRotation has the following parameter(s):
- int matrix[m][n]: a 2D array of integers
- int r: the rotation factor
Prints
It should print the resultant 2D integer array and return nothing. Print each row on a separate line as space-separated integers.
Input Format
The first line contains three space separated integers, , , and , the number of rows and columns in , and the required rotation.
The next lines contain space-separated integers representing the elements of a row of .

Explanation #03
All of the elements are the same, so any rotation will repeat the same matrix.
