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 ...
public class LongestPalindromicSubString3 { public static String longestPalindrome(String s) { if (s.isEmpty()) { return null; } if (s.length() == 1) { return s; } String longest = s.substring(0, 1); for (int i = 0; i < s.length(); i++) { // get longest palindrome wit...
public class LongestPalindromicSubString3 { public static String longestPalindrome(String s) { if (s.isEmpty()) { return null; } if (s.length() == 1) { return s; } String longest = s.substring(0, 1); for (int i = 0; i < s.length(); i++) { // get longest palindrome wit...
5. Longest Palindromic Substring 提交网址:https://leetcode.com/problems/longest-palindromic-substring/ Total Accepted: 108823 Total Submissions: 469347 Difficulty: Medium Given a string S, find the longest palindromic substring in S. You may assume that the maximum length of S is 1000, and there...
public String longestPalindrome(String s) { String ans = ""; int max = 0; int len = s.length(); for (int i = 0; i < len; i++) for (int j = i + 1; j <= len; j++) { String test = s.substring(i, j); if (isPalindromic(test) && test.length() > max) { ...
Here is a recursive solution: Code: String longestSequence (String s) { if (s.length == 0) return ""; char c = s.charAt (0); String subs = s.replaceAll ("(" + c + "+).*", "$1"); int susi = subs.length (); String rest = longestSequence (s.substring (susi)); if ...
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” ...
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 lon...
如果所有character出现次数都不小于k,那么说明整个string就是满足条件的longest substring,返回原string的长度即可;如果有character的出现次数小于k,假设这个character是c,因为满足条件的substring永远不会包含c,所以满足条件的substring一定是在以c为分割参考下的某个substring中。所以我们需要做的就是把c当做是split的参考,...
Java String Java Characters Math 1. Overview In this tutorial, compare ways to find the longest substring of unique letters using Java. For example, the longest substring of unique letters in “CODINGISAWESOME” is “NGISAWE”. 2. Brute Force Approach ...
