题目链接:Longest Palindromic Substring 1. 问题描述 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. 2. 各种解法复杂度 暴力枚举:O(N^2) 记忆化搜索:O(N
1 问题描述 给定一个字符串,求它的最长回文子串的长度. 2 解决方案 2.1 中心扩展法 此处,首先枚举出回文串的中心位置,然后,再在该位置上分别向左和向右扩展,记录并更新得到的最长回文串的长度. package com.liuzhen.string_1; import java.util.Scanner; public class StringLongestPalindrome { /* * 参数A:给定字符串 * 函数功能:返回字符串A中最长回文串的长度 */ public int get

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. 这道题让我们求最长回文子串,首先说下什么是回文串,就是正读反读都一样的字符串,比如 "bob", "level", &q
1.题目 Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Example 1: Input: "babad" Output: "bab" Note: "aba" is also a valid answer. Example 2: Input: "cbbd
