1、问题描述 这个问题来自leetcode中的Longest Substring Without Repeating Characters,诚如标题所述,我们需要寻找的是在一个字符串中,没有重复字符的最长字串。我们假定字符串中的字符只由$a$~$z$这26个字符构成。例如,对于字符串"$abcabcbb$",它的无重复字符最长字串是"$abc$",长度为3;对于字符串"$bbbb$"...

LeetCode 5. Longest Palindromic Substring 题目链接 最长回文子串 - 力扣 (LeetCode) Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Example 1: Example 2: 题目范围小于1000所以可以用n^2的算法 枚举中心点,用两个指针向......
Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Example: Input: "babad" Output: "bab" Note: "aba" is also a valid answer. Example: Input: "cbbd" Output: "bb" ...
求两字符串的连续最大公共子字符串(The Longest Common Substring) 这个LCS问题就是求两个字符串最长公共子串的问题。解法就是用一个矩阵来记录两个字符串中所有位置的两个字符之间的匹配情况,若是匹配则为1,否则为0。然后求出对角线最长的1的序列,其对应的位置就是最长匹配子串的位置。如图1所示,在对角线上,...
This is a like a sliding window to find the longest substr, if we put the letters in an array, then check the next letter, if it is in the array, then sliding the window, otherwise, put the value in the array set. code:
Click me to see the sample solution 7. Replace 'not'...'poor' with 'good'. Write a Python program to find the first appearance of the substrings 'not' and 'poor' in a given string. If 'not' follows 'poor', replace the whole 'not'...'poor' substring with 'good'. Return the ...
