Below image shows the output of the above longest palindrome java program. We can improve the above code by moving the palindrome and longest lengths check into a different function. However, I have left that part for you. :) Please let me know if there are any other better implementations ...
A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward as forward, such as madam. Write a java program to find the longest palindrome present in a given string. For example, in the string <span class="ant">a

最长回文串(longest palindrome)-java 最长回文串 longest palindrome 题目 分析 解答 题目 给定一个包含大写字母和小写字母的字符串,找到通过这些字母构造成的最长的回文串。 在构造过程中,请注意区分大小写。比如 “Aa” 不能当做一个回文字符串。 注意: 假设字符串的长度不会超过 1010。 示例 1: 代码模板: ...
Java实现如下: 1publicclassSolution {2publicString longestPalindrome(String s) {3intlen=s.length();4if(len<=1){5returns;6}7intLen=1,maxLen=1;8inti,j;9String str=String.valueOf(s.charAt(0));10if(s.charAt(0)==s.charAt(1)){11str=s.substring(0,2);12maxLen=2;13}14for(i=1;...
public String longestPalindrome(String s) { int maxLength = 0; int maxStart = 0; int len = s.length(); //i是字符串长度 for(int i = 0; i < len; i++){ //j是字符串起始位置 for(int j = 0; j < len - i; j++){
