给定一个 n × n 的二维矩阵表示一个图像. 将图像顺时针旋转 90 度. 说明: 你必须在原地旋转图像,这意味着你需要直接修改输入的二维矩阵.请不要使用另一个矩阵来旋转图像. 示例 1: 给定 matrix = [ [1,2,3], [4,5,6], [7,8,9] ], 原地旋转输入矩阵,使其变为: [ [7,4,1], [8,5,2], [9,6,3] ] 示例 2: 给定 matrix = [ [ 5, 1, 9,11], [ 2, 4, 8,10], [13, 3, 6, 7], […

给定一个 n × n 的二维矩阵表示一个图像.将图像旋转 90 度(顺时针).注意:你必须在原矩阵中旋转图像,请不要使用另一个矩阵来旋转图像.例 1:给出的输入矩阵 = [  [1,2,3],  [4,5,6],  [7,8,9]],旋转输入矩阵,使其变为 :[  [7,4,1],  [8,5,2],  [9,6,3]]例 2:给出的输入矩阵 =[  [ 5, 1, 9,11],  [ 2, 4, 8,10],  [13, 3, 6, 7],  [15,14,12,16]], 旋转输入矩阵,使其…

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? 在计算机图像处理里,旋转图片是很常见的,由于图片的本质是二维数组,所以也就变成了对数组的操作处理,翻转的本质就是某个位置上数移动到另一个位置上,比如用一个简单的例子来分析: 1  2  3 7  4  1 4  5  6 -…

题目: You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees (clockwise). (Medium) Follow up:Could you do this in-place? 分析: 就是在纸上画一画找到对应关系即可, newMatrix[i][j] = matrix[n - 1 - j][i]; 所以简单的方法就是开一个新数组,按照对应关系填入新数组,再拷贝回原来的数组…

Rotate Image 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? 思路:事实上就是旋转数组.没有什么难度.代码例如以下: public class Solution { public void rotate(int[][] matrix) { int[][] a…

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…

1.6 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? LeetCode中的原题,请参见我之前的博客Rotate Image 旋转图像.…

Given a linked list, rotate the list to the right by k places, where k is non-negative. Example 1: Input: 1->2->3->4->5->NULL, k = 2 Output: 4->5->1->2->3->NULL Explanation: rotate 1 steps to the right: 5->1->2->3-&g…
