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
