LeetCode is one of the platforms I use to improve my programming and problem-solving skills. It provides a wide range of problems covering algorithms, data structures, databases, and other areas of computer science.

I am using this space to keep track of the problems I practice and the lessons I learn along the way. Rather than focusing only on solving a large number of problems, my goal is to understand the concepts, learn from mistakes, and gradually become better at approaching unfamiliar problems.
