You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? 原地图像顺时针旋转90度.由于要求空间复杂度是常数,因此应该迭代旋转操作. class Solution { public: void rotate(vector<vector<int> > &mat
[字符串与数组] Q:Given an image represented by an NxN matrix, where each pixel in the image is 4 bytes, write a method to rotate the image by 90 degrees Can you do this in place? 题目:假定一幅图像能用NxN的矩阵表示,每个像素是四字节.写一个算法将图像旋转90度,你能否在原地进行操作(也即不分配额外的存储空间)? 解答: 我们不知
