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 ...

Given "pwwkew", the answer is "wke", with the length of 3. Note that the answer must be a substring, "pwke" is a subsequence and not a substring. 解法1: 核心思想是当发现有重复的字母,就把重复字母第一次出现位置以及之前的字母都删掉,这样就保证剩下的string中没有重复的字母了。用hashmap...
Longest Substring with At Most Two Distinct Characters 最新思路解法:https://yanjia.me/zh/2018/12/... Given a string, find the length of the longest substring T that contains at most 2 distinct characters. For example, Givens = “eceba”, T is"ece"which its length is 3. 哈希表法 复杂...

5. Longest Palindromic Substring Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Example 1: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Input: "babad" Output: "bab" Note: "aba" is also a valid answer. Example...
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 ...
