Given a stringS, find the longest palindromic substring inS. You may assume that the maximum length ofSis 1000, and there exists one unique longest palindromic substring. 题解: 第一种方法就是挨个检查,维护全局最长,时间复杂度为O(n3),会TLE。 代码如下: 1publicString longestPalindrome(String s) {...
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. 暴力法 Brute Force 复杂度 时间O(n^3) 空间 O(1) 思路 暴力法就是穷举所有子字符串的可能,然后依次按位判断其是否是...

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. Example Given thestring = "abcdzdcab", return"cdzdc". Challenge O(n2) time is acceptable. Can you do it in O...
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)。

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. 时间复杂度为O(N²)的算法 leetcode-最长回文子串 5. 最长回文子串 给定一个字符串 s,找到 s 中最长的回文...
方法一:暴力法 思路 逐个检查所有的子字符串,看它是否不含有重复的字符。 算法 假设我们有一个函数 boolean allUnique(String substring) ,如果子字符串中的字符都是唯一的,它会返回true,否则会返回false。 我们可以遍历给定字符串 s 的所有可能的子字符串并调用函数 allUnique。 如果事实证明返回值为...leet...
简介:需求: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. 如果一个字符串从左向右写和从右向左写是一样的,这样的字符串就叫做palindromic string 判断回文数,中间开花。
