LeetCode 48. Rotate Image(旋转图像) You are given annxn2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? 题目标签:Array 这道题目给了我们一个n * n的矩阵,让我们旋转图片。题目要求in-place,所以就不能用额外的空间了。一开始...
https://leetcode.com/problems/rotate-image/ You are given annxn2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? 解题思路: 先写一个不是in-place的。多写几个例子,就能看出来旋转后的矩阵和原矩阵下标的关系就是:result[j][ma...
...关键词: 1、matrix: 矩阵 2、2D matrix: 二维矩阵 3、rotate: 旋转 4、clockwise: 顺时针 5、90 degrees: 90度 即:我们需要将一个二维矩阵顺时针旋转...解题思路 规律很容易得出来,难得是不能定义一个新的二维矩阵,所以这里先生成一个目标的一维矩阵,然后通过一定规律再依次赋值给原矩阵。...[i*...
