        were heavily based on applying JavaScript concepts in real-world projects.
        They also included a hard Leetcode problem involving concepts of arrays, 
        priority queues, and sorting, which was difficult to even come up with a brute-force approach 
        for.This made me realize I need to seriously improve my DSA skills.

          1) Improve DSA skills – don’t just memorize solutions.
