题目:矩阵置0 难度:Easy 题目内容: Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in-place. 翻译: 给定一个m x n矩阵,如果一个元素是0,就把它的整行和列设为0. 要求:就地置0. Example 1: Input: [ [1,1,1], [1,0,1], [1,1,1] ] Output: [ [1,0,1], [0,0,0],
给一个矩阵mat,每个格子都是0或1,翻转一个格子会将该格子以及相邻的格子(有共同边)全部翻转(0变为1,1变为0) 求问最少需要翻转几次将所有格子全部置为0. 这题的重点是数据范围,比赛结束看了眼数据范围想把自己锤死= = m == mat.length n == mat[0].length 1 <= m <= 3 1 <= n <= 3 mat[i][j] is 0 or 1. 也就是....最多也就9个格子.....暴力怎么都能搞出来的..... 首先分析每个格子要么
题目: Given a n x n matrix where each of the rows and columns are sorted in ascending order, find the kth smallest element in the matrix. Note that it is the kth smallest element in the sorted order, not the kth distinct element. Example: matrix = [ [
Write an efficient algorithm that searches for a value in an m x n matrix. This matrix has the following properties: Integers in each row are sorted from left to right. The first integer of each row is greater than the last integer of the previous ro
Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in place. public class Solution { public void setZeroes(int[][] matrix) { if(matrix==null){ return; } int m=matrix.length; int n=matrix[0].length; List<Integer> r=ne
理解CSS3 transform中的Matrix(矩阵) by zhangxinxu from http://www.zhangxinxu.com 本文地址:http://www.zhangxinxu.com/wordpress/?p=2427 一.哥,我被你吓住了 打架的时候会被块头大的吓住,学习的时候会被奇怪名字吓住(如"拉普拉斯不等式").这与情感化设计本质一致:界面设计好会让人觉得这个软件好用! 所以,当看到上面"Matrix(矩阵)"的时候,难免会心生畏惧
