LeetCode之Longest Substring Without Repeating Characters

这次的题目是找出字符串中最长不重复子串，一开始还以为跟最长匹配子串类似，需要用到动态规划呢，结果还是自己想太多了，偷看了一眼Tag，才发现只需要用hashmap和两个指针就能搞定。 算法的主要思想是：初始化两个指针head和tail，分别指向字符串初始位置0，并初始化一个hashmap，key为考察中的字符，value为对应字符所在位置。然后一个while循环，直至tail到达字符串尾部，在循环的每一步，首先会检查s[tail]是否存在于hashmap中，如果没有，则插入，否则找出s[tail]之前出现过的
