Question

convert the for loop into x86 assembly..

            int[][] rotateMatrixBy90Degree(int[][] matrix, int n) {

//We need to run the loop for only half the number of rows as it represents one quarter or quadrant

for (int layer = 0; layer < n / 2; layer++) {

//In every iteration, we reduce number of columns to be swapped by computing first and last column index. We are rotating counter clockwise.

                                    int first = layer; //start column pixel of current row

                                    int last = n - 1 – layer; //last column pixel of current row

                                    for (int i = first; i < last; i++) {

                                                int offset = i – first;

                                                int top = matrix[first][i];

                                                matrix[first][i] = matrix[last - offset][first];

                                                matrix[last - offset][first] = matrix[last][last - offset];

                                                matrix[last][last-offset] = matrix[i][last];

                                                matrix[i][last] = top;

                                    }

                        }

                        return matrix;

            }

I am trying to rotate image 90 degree clockwise.
