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…

题目大意是传入一条字符串,计算出这样的这样一条子字符串,要求子字符串是原字符串的连续的某一段,且子字符串内不包含两个或两个以上的重复字符.求符合上面条件的字符串中最长的那一条的长度. 首先注意到任意一条无重复子字符串的任意子字符串应该也满足无重复这一特性.因此这个问题可以用动态规划解决. 需要先计算出字符串s的每个元素对应的首个重复字符的下标,字符串中下标为i的元素的首个重复字符的下标j应该满足j > i && s[i] == s[j],且是满足这些条件中的最小值.比如asaa中下标…
