Write a static method rotateMatrix that accepts a two-dimensional (2D) integer array as square matrix NxN (i.e., N rows and N columns), and returns a 2D integer array as square matrix after rotating the input matrix by 90 degrees in clockwise direction. 

 For example, if input 4x4 integer matrix is: 

{{1, 2, 3, 4},   

 {5, 6, 7, 8},   

 {9, 10, 11, 12},   

 {13, 14, 15, 16}} 

After rotation, rotateMatrix should return the following 2D integer array: 

{{13, 9, 5, 1},   

 {14, 10, 6, 2},   

 {15, 11, 7, 3},   

 {16, 12, 8, 4}} 

 

For example, if input 2x2 integer matrix is: 

{{1, 2},     {5, 6}} 

After rotation, rotateMatrix should return the following 2D integer array: 

{{5, 1},   

 {6, 2}} 

Note: NxN matrix is declared as "int array_name[N][N];". E.g., 4x4 matrix would be "int array_name[4][4];".
