Inversions Problem | Fenwick Tree (BIT) | Episode 7 | Dry Run | Codeforces

🚀 Codeforces Inversions Problem | Fenwick Tree (BIT) | Episode 7 📌 Problem : https://codeforces.com/edu/course/2/l... 🚀 Subscribe to Our channel:    / @vijay_algorithms   Welcome to Episode 7 of my *Fenwick Tree (Binary Indexed Tree - BIT)* series! In this video, we solve a *Codeforces Inversions Problem* using the concepts of **Inversion Counting + Fenwick Tree (BIT)**. The goal is to understand the problem from scratch, build the intuition, and then implement the solution through *live coding* with a detailed dry run. 📌 What You'll Learn: ✅ What is an Inversion? ✅ How to Identify Inversions ✅ Building the Intuition ✅ Fenwick Tree / BIT Approach ✅ Frequency-Based Queries ✅ Detailed Dry Run ✅ Step-by-Step C++ Implementation ✅ Time & Space Complexity 💡 Inversion counting is a fundamental concept in Competitive Programming and is closely related to many problems involving **ordering, relative positions, and frequency queries**. This episode will help you build a strong foundation for solving *Inversion + BIT* problems in Codeforces and other competitive programming platforms. 🎯 Perfect for: • Codeforces • Competitive Programming • Fenwick Tree / BIT • Inversion Count • Data Structures & Algorithms • C++ Problem Solving • Coding Interviews 👍 If you found this video helpful: ❤️ Like the video 📤 Share it with your friends 💬 Comment your doubts or suggestions 🔔 Subscribe for more DSA, Algorithms & Competitive Programming content.
