LeetCode Longest Substring Without Repeating Characters 最长不重复子串

题意:给一字符串,求一个子串的长度,该子串满足所有字符都不重复.字符可能包含标点之类的,不仅仅是字母.按ASCII码算,就有2^8=128个. 思路:从左到右扫每个字符,判断该字符距离上一次出现的距离是多少,若大于max,则更新max.若小于,则不更新.每扫到一个字符就需要更新他的出现位置了.这里边还有个注意点,举例说明: 假如有长为16串 s="arbtbqwecpoiuyca" 当扫到第2个b时,距离上一个b的距离是2:(直接减) 当扫到第2个c时,距离上一个c的距离是6:(直接减
