LeetCode——Rotate Image(二维数组顺时针旋转90度) 问题: You are given annxn2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? 分析: 二维数组a[n][n]顺时针旋转90度,要解决这个问题,无疑,第一件事儿就是找规律。 当n=1时,...
Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? class Solution { public: void rotate(vector<vector<int> > &matrix) { //方法1:tempMatrix[j][n-1-i] = matrix[i][j]; 置换 //方法2:先对角线翻转,再中间线上下翻转 int n,i,j,temp; n=matrix.size...
Rotate the image by 90 degrees (clockwise). Note: You have to rotate the imagein-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the rotation. 翻译:你有一个n*n 的2D矩阵表示一个图像。 将图像旋转90度(顺时针)。 注意: 你必须...
You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Note:You have to rotate the image in-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the rotation. 难度:Medium 2 题目样例...
Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? 简单的说就是给出一个n*n的二维数组,然后把这个数组进行90度顺时针旋转,而且不能使用额外的存储空间。 最初拿到这道题想到的就是找出每个坐标的旋转规律。假设我们是2*2的矩阵: ...

1. Rotate image 90 degrees, 180 degrees, and 270 degrees. In this example, we will read an image, and then rotate it different angles liek 90 degrees, 180 degrees and 270 degrees. For each rotation with given degrees, we will save the image. ...
