u are given annxn2D 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. Example 1: Given input matrix ...
Given a list,rotatethe list to the right by k places, where k is non-negative.For example:Given 1->2->3->4->5->NULL and k = 2,return 4->5->1->2->3->NULL.1. 首先,需要先遍历一遍拿到 java leetcode 原创 marstorm08

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。
