1371. Find the Longest Substring Containing Vowels in Even Counts | Leetcode Daily Challenge | JAVA

In this video, we will solve LeetCode problem number 1371, titled “Find the Longest Substring Containing Vowels in Even Counts.” This problem is categorized as Medium difficulty, and the objective is to find the longest substring of the input string where each vowel (‘a’, ‘e’, ‘i’, ‘o’, ‘u’) appears an even number of times.

We will begin by explaining the problem and its requirements. The key idea to solving this problem efficiently involves using a bitmask to track the parity of the vowels. By leveraging a HashMap to store the first occurrence of each bitmask configuration, we can find the longest valid substring where all vowels have an even count.

By the end of the tutorial, you’ll understand how to implement this approach to solve the problem efficiently.
