I need to rotate the array by 90 degrees without using another array. I'm having issues with this code and am unsure why. In Java

//rotate a matrix 90 degrees without replacing the matrix public class MatrixNoReplacement { public static void rotate(int[][] matrix, int n){ for(int layer=0; layer

//save the top left of the matrix int top = matrix[first][i];

//shift left to top; matrix[first][i]=matrix[last-offset][first];

//shift bottom to left matrix[last-offset][first]=matrix[last][last-offset]; //shift right to bottom matrix[last][last-offset]=matrix[i][last]; //rightmost top corner matrix[i][last]=top; } }

static void matrixPrinter(int matrix[][], int n) { // int n = 4;

for (int i = 0; i

public static void main(String[] args) { int n = 4; int matrix[][] = { { 1, 2, 3, 4 }, { 5, 6, 7, 8 }, { 9, 10, 11, 12 }, { 13, 14, 15, 16 } }; // calling method rotateMatrixClockwise on the array twoDim in main method rotate(matrix, n); // calling method matrixRotateRunner on the array twoDim in main method matrixPrinter(matrix, n); }

}
