01 看题和准备 今天介绍的是LeetCode算法题中Medium级别的第2题Longest Substring Without Repeating Characters(顺位题号是3)。给定一个字符串,找到最长无重复字符子字符串的长度。例如: 输入:“abcabcbb” 输出:3 说明:答案是“abc”,长度为3。 输入:“bbbbb” 输出:1 说明:答案是“b”,长度为1。 输入:“...
假设当窗口的右边界向右滑动添加一个字符后,窗口中的子串存在重复的字符,按照解法二的方法,则会将窗口的左边界向右滑动一个字符直到窗口中不存在重复字符为止。这样的做法其实是不高效的,比如重复的字符位于子串的右半部分,那么至少需要迭代len(substring)/2len(substring)/2次才能使得窗口包含的子串不包含重复的字符。

Given a string, find the length of the longest substring without repeating characters. Examples: Given “abcabcbb”, the answer is “abc”, which the length is 3. Given “bbbbb”, the answer is “b”, with the length of 1. Given “pwwkew”, the answer is “wke”, with the length ...
Given “pwwkew”, the answer is “wke”, with the length of 3. Note that the answer must be a substring, “pwke” is a subsequence and not a substring. 题意就不说了,这道题是求的是最大的不重复的子串,求解重复子串可以类似采用最长公共子串的解法。
