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...
Can you solve this real interview question? Find the Longest Substring Containing Vowels in Even Counts - 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' mus
Now we insert A to different indexes in BC and CB. BC : ABC , BAC , BCA CB : ACB, CAB, CBA so thats how we got all permutations of ABC. It may look tricky but once you practice the solution, you will be able to understand it better. Java program to find all Permutations of S...
