Sort Integers by 1 Bits | Easy Guide & Code 🧮

In this video, I explain the intuition and approach behind LeetCode 1356 – Sort Integers by the Number of 1 Bits in a simple and beginner-friendly way.

We learn how to:
Count the number of set bits (1s) in the binary representation of each number.
Use sorting and a map to group numbers based on their bit count.
Maintain ascending order when multiple numbers have the same number of 1s.
Understand the logic clearly with a step-by-step dry run and code explanation.

This problem is great for improving your bit manipulation, sorting, and data structure concepts.

If you are preparing for coding interviews or improving problem-solving skills, this will help you build strong intuition.
