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...

LeetCode题解——Longest Palindromic Substring
题目:给定一个字符串S,返回S中最长的回文子串。S最长为1000,且最长回文子串是唯一。解法:①遍历,对于每个字符,计算以它为中心的回文子串长度(长度为奇数),同时计算以它和右边相邻字符为中心的回文子串长度(长度为偶数)。时间为O(N2)。②另外,有一个很奇妙的算法,称为Manacher算法,参考 ...

js中 substr(), substring(), slice()的区别
一、作用三者都是基于原字符串创建新字符串的方法。接收一到两个参数,第一个参数截取字符串的开始位置(字符下标,从0开始),第二个参数因方法不同而不同,后面不同点会说到。另外,三个方法都不会修改原字符串的值。二、相同点都可以传入一个或两个参数只传入一个参数时,都表示从指定下标,截取字符串长度,直到字符串...
