Rotate Image Rotate a matrix clockwise, 90 degree. do it in-place. how to do it in place? remember, do it in place doesn’t mean that we don’t need extra space. in fact, we do. so if we takes an element and put it down in its new place, the original element here will be ...
public void rotate(int[][] matrix) { for (int i = 0; i < matrix.length; i++) { for (int j = i; j < matrix[0].length; j++) { int temp = matrix[i][j]; matrix[i][j] = matrix[j][i]; matrix[j][i] = temp; } } for (int i = 0; i < matrix.length; i++) ...
Input MatrixObject <active> Specifies the input matrix. Rotate Degree degree Input int ccw90 Specifies the degree and direction for the matrix rotation. Option list: ccw90:CCW90 Rotates the matrix 90 degrees counter-clockwise. ccw180:CCW180 Rotates the matrix 180 degrees counter-...
1. 旋转image by 90 degree, 【顺时针】 最好do it in place. clockwise rotate的基本idea 1 2 3 7 4 1 4 5 6 ---> 8 5 2 7 8 9 9 6 3 先transpose 再flip symmetric 所以需要掌握transpose a matrix以及flip a matrix. 说实话我很讨厌这个方法,因为感觉这个和我们生活中旋转的方式不太一样。
