In this video, I walk through the solution to Codeforces problem 2184A – Social Experiment, explaining both the intuition and the implementation step by step using C++. We break down the problem, identify key observations, and apply an efficient approach that works within the given constraints. I’m still learning and improving, so if you know a more optimal approach, a cleaner implementation, or have tips/tricks to solve this problem differently, I’d love to hear your feedback in the comments! 📌 Language Used: C++ 📌 Difficulty: Beginner–Intermediate If this helped you, consider liking, commenting, and subscribing for more Codeforces walkthroughs and competitive programming content!
