LeetCode #3. Longest Substring Without Repeating Characters

题意：计算一个字符串的中的最长的不含有重复字母的长度解法：尺取法的裸题了，维护2个指针l,r, 不断移动r指针，同时检查[l,r]是不是存在重复的了，如果存在就移动l指针了 class Solution {public:int lengthOfLongestSubstring(string s) {int n = s.size();int l=0, r=0;set<char> S;in

leetcode 题解 3. 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。

3. Longest Substring Without Repeating Characters 无重复字符的最长子串

https://leetcode.com/problems/longest-substring-without-repeating-characters/description/ 题目大意:给一个字符串,要求出最长的不含重复字符子串(要求连续,不是子序列). 解题思路:不重复,利用哈希表.hash是以字符的ASC为下标的数组,对应存储该字符最后出现的位置. 设一个标记start,然后一次遍历

leetcode03-Longest Substring Without Repeating Characters

题目给定一个字符串 s ，请你找出其中不含有重复字符的最长子串的长度。示例 1: 输入: s = “abcabcbb” 输出: 3 解释: 因为无重复字符的最长子串是 “abc”，所以其长度为 3。分析很直观的思路就是遍历字符串，如果子串中没有重复元素那么长度不停加1，同时我们应该记录不重复子串的开始坐标，不重复子串的开始坐标一定是刚刚出现的重复元素对应的坐标＋1，同时一定要注意

CodeForce[1500-2000]——1950E Nearly Shortest Repeating Substring

codeforces刷题日记题目大意：给你一个长度为n的字符串s，要寻找一个长度最小的字符串k，能够让字符串k进行1或多次的拼接，让拼接成的字符串和字符串s长度相等，且至多一个字母不一样。求k的最小长度。思路：从1到n遍历k的长度i，如果i整除，就跳过，这时s被分成了n/i段，取出第一段和最后一段。如果这两段相等，那其他段必定和这两段一样（不一样的值字母允许存在一个），才符合条件。要是
