🚀 CSES Bit Counting Problem – Solve it in O(log n)!
In this video, I tackle the CSES Bit Counting problem with an efficient O(log n) solution that works even for n = 10¹⁵! 🔥
🔍 Problem: Count the total number of 1-bits in the binary representations of all numbers from 1 to n. A brute-force approach would fail, but we’ll use bit manipulation, memoization, and mathematical pattern recognition to optimize it!
👨💻 What you'll learn:
✅ Advanced bit manipulation techniques
✅ Memoization for optimization
✅ Mathematical insights into binary representation
💡 Whether you're preparing for coding interviews or sharpening your CP skills, this problem is a must-solve! Let’s break it down step by step.
