题目如下: 解题思路:很经典的动态规划题目,但是用python会超时,只好用C++了. 代码如下: class Solution { public: int longestPalindromeSubseq(string s) { ][] = {}; ; ;i >=;i--){ ;j<s.length();j++){ dp[i][i] = ; if (s[i] == s[j]){ dp[i][j] = dp[i][j] > dp[i+][j-]+ ? dp[i][j] :dp[i+][j-…

题目: 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. 思路:用Manacher算法得到最大回文子串的长度,得到带#的最大回文子串,用split剔除#后转化成String形式输出即可. public…

题目描述: 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. 解题分析: 之前百度实习生面试也被问到这个问题.这个题比较简单.就是在分别考虑对称字符字串为奇数和偶数的情况,在不超过字符串范围的情况下向…
