In our java program, we will iterate over the input string with mid as 1st place and check the right and left character. We will have two global variables to save the start and the end position for palindrome. We also need to check if there is already a longer palindrome found sinc...
最长回文子串C++实现 java实现 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"isalso a valid answer. Example2:Input:"cbbd"Output:"bb" 给定一个字符串 s,找到 s 中最长的...

Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Input: "babad" Output: "bab" Note: "aba" is also a valid answer. 暴力算法就是找到所有substring, 每个都进行isPalindrome的检查。时间复杂度是O(N^3). N^2个substring, ...
LeetCode刷题，是为了获得面经，这是题目5的java实现解法 工具/原料 笔记本 eclipse 方法/步骤 1 题目叙述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.2 本体可以使用动态规划去...
longest substring可能只包含一种char, 或者两种char. 1. 只包含一种Char, 强制保持p1 == p2 2. 出现两种char, 保证p1 <= p2, 为了计算方便 3. 出现第三种char的时候,i - (p1+1) + 1 = i- p1 直接计算出当前substring长度。同时保证p1<=p2. ...
Java Code:import java.util.*; // Define a class named Main public class Main { // Method to find the longest substring that appears at both ends of the given string public String appearInBothEnds(String stng) { int l = stng.length(); // Get the length of the given string String ...
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" Output: "bb" ...
