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? 在原址上进行将矩阵旋转90度。 如图,把 1 2 3调换到原来的 最后一列3 6 9,原来的3 6 9 旋转到最底部,同理原理啊的7 8 9旋转到第一列,中间的一个元素不变。 这样我们只要发现小标之间的关系,在纸上推一推...
题出自https://leetcode.com/problems/rotate-image/ 内容为: You are given annxn2D matrix representing an image. 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。
