Hello, Codeforces community

The Club of Programmers, IIT BHU is excited to announce the launch of COPS YouTube channel.

This channel will largely focus on being a helping hand to all our fellow mates who are eagerly working in the field of Competitive Programming, Machine Learning, and Development.

The highlight of the channel will be meticulously crafted editorials and tutorials for some must-know Competitive Programming, Machine learning, and Web Development topics. Additionally, we will also pour out content for beginners to enable them to kickstart their journey in the CS fields above.

So, for everyone looking for a place to get their share of fun while coding, check out our YouTube channel for more! It will contain all resources needed for our community with lots of learning waiting for you!
