We can improve the above code by moving the palindrome and longest lengths check into a different function. However, I have left that part for you. :) Please let me know if there are any other better implementations or if it fails in any case....

Difficulty: Medium Given a string s, find the longest palindromic(回文) substring in sS. You may assume that the maximum length of s is 1000, and there exists one unique longest palindromic substring. 推荐解法3,直观,有效,好理解 方法一:暴力搜索(O(N³)) 这个思路就很简单了,就是直接求出每...
Substring, also called factor, is a consecutive sequence of characters occurrences at least once in a string. Now your task is simple, for two given strings, find the length of the longest common substring of them. Here common substring means a substring of two or more strings. ...
Given a string S, find the longest palindromic substring in S. You may assume that the maximum length of S is 1000, and there exists one unique longest palindromic substring. 分析: 方法1:动态规划,建议循环用while,for容易超时,时间复杂度为O(n^2)。
{strings1="bbb"; Solution s; cout<<s.longestPalindrome(s1)<<endl; } 思路3. 思路来源于此 http://www.leetcode.com/2011/11/longest-palindromic-substring-part-ii.html 不过原文的陈述仔细研究了一下,有一些地方让人着实费解,所以自己决定重写一遍。
LeetCode 5: Longest Palindromic Substring 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: The common way (O(n2)O(n^2)O(n2)): start from i, i-th is the c......
Longest Palindromic Substring Desicription Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Example: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Input: "babad" Output: "bab" Note: "aba" is also a valid answer. ...
Given a string S ,find the longest palindromic substringin S. You may assume that the maximum length of S is 1000, and there exists one unique longest palindromic substring. 什么是回文串 这种对称的,从前往后拼写和从后往前拼写一样的字符,分为奇数长度和偶数长度 “abba” “abcba” “abcddcba”...
