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. https://leetcode.com/problems/longest-palindromic-substring/ 暴力,从头到底遍历,以当前的数为回文中心,判断是否为回文。 每一轮遍...
Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. 题目的意思是输入一个字符串,我们要找到这个字符串的最长的满足回文条件的子字符串。 回文的意思就是反转字符串后和原字符串相等。
Write a JavaScript function that returns the longest palindrome in a given string.Note: According to Wikipedia "In computer science, the longest palindromic substring or longest symmetric factor problem is the problem of finding a maximum-length contiguous substring of a given string that is also a...
Given a string S, find the longest palindromic substring in S. 题义很明细:求一个字符串S中的最长回文! 基本想法: for-loop i从0 – (n-1)遍历该字符串,从S[i] 或者 S[i+1]开始,向字符串S的两侧展开,判断是不是回文。如果是,再和当前的最长回文比较,如果更长,则替换当前最长的回文。 代码如下...
Leetcode-Medium 5. Longest Palindromic Substring,题目描述给定一个字符串s,找到s中最长的回文子串。你可以假设s长度最长为1000。Example1:Input:ut:"cbbd"Output:"bb"思路假如输入的字符串长度就...
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: 遍历该字符串每一个位置,并判断以该位置为中位点的最长回文串的长度,复杂度为O(n^2)。 要注意如果回文串是奇数长...
Longest Palindromic Substring LeetCode—5. Longest Palindromic Substring 题目https://leetcode.com/problems/longest-palindromic-substring/description/ 寻找最长回文子串。 思路及解法 在字符串中首先选择一个点,从这个点开始向两边扩展开去,不断比较两端的字符是不是相等。需要注意的是,回文子串的长度可奇可 ...
