LEETCODE 1542: Longest Awesome Substring | Bitmask Trick Explained
Question Link: https://leetcode.com/problems/find-lo...
In this video, we break down the complete intuition behind LeetCode 1542: Longest Awesome Substring, a popular bitmask-based problem that checks when a substring can form a palindrome.
You will learn:
✔ How bitmasking tracks odd/even occurrences
✔ The role of toggling digits (0–9) to find valid palindromes
✔ Using hashing to store earliest bitmask positions
✔ Achieving an optimal O(n × 10) solution
✔ Why this is one of the smartest applications of bitmask in strings
This explanation will help you master a pattern frequently asked in coding interviews and competitive programming contests.
