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 Let’s start with a naive approach. To begin with,we can examine each substring wh...
Given a string, find the length of the longest substring without repeating characters. 给一个字符串,求出最长的无重复字符的子字符串长度。 Examples: Given"abcabcbb", the answeris"abc", which the lengthis3. Given"bbbbb", the answeris"b",withthe lengthof1. Given"pwwkew", the answeris"wke...
Given the string s, return the size of the longest substring containing each vowel an even number of times. That is, ‘a’, ‘e’, ‘i’, ‘o’, and ‘u’ must appear an even number of times. Example 1: Input: s = "eleetminicoworoep" Output: 13 Explanation: The longest substr...
Explanation: The longest substring is "leetminicowor" which contains two each of the vowels: e, i and o and zero of the vowels: a and u. Example 2: Input: s = "leetcodeisgreat" Output: 5 Explanation: The longest substring is "leetc" which contains two e's. Example 3: Input: s...
