Longest Substring Without Repeating Characters

这一题的目标是找出字符串中最长的子串，要求字符串无重复。先是一个错误的解法：首先找出最长的无重复子串从该子串的下一个字母开始，继续执行判断过程。但这一方法存在一定的漏洞，对于其中的测试用例：“dvdf”，如果采用以上思路，则首先得到子串“dv”；再从d开始判断，得到子串“df”，此时处理过程结束。但以上过程并不能得到最优结果“vdf”。因此为解决这种情况，解法又回到了暴力方法。暴力法的思路如下：使

查找给定字符串的最长不重复子串。方法一该方法很直接，依次从每一个字符开始，向后逐个遍历，直到遇到重复的字符为止。判断字符是否重复，用到了hash数组，可以在常数时间内判断当前字符在本次循环中是否访问过，由于针对的是ASCII字符集，故使用的hash数组大小为256.intlengthOfLongestSubstring(string&s){intn=s.size();intmaxLen=(0==n

LeetCode题解-3-Longest Substring Without Repeating Characters

解题思路首先要读懂题目，它要求的是找到最长的子串，并且子串中没有出现重复的字符。我的想法，是用一个map存储每个字符最后出现的位置，还要有个变量start，它用来记录上一次出现重复的位置，如果当前字符上一次出现的位置比start小，那么说明中间出现了重复，不能当成有效的子串。记得就是在扫描结束后，再判断一下最后一段子串。给个图简单说明一下。参考源码publicclassSolution{publi
