Q:what i need to study to be gm in codeforces from the begining?everything about the roadmap

A:To become a successful CodeForces GM, you need to have a strong understanding of algorithms, data structures, and problem solving. You should also be familiar with the CodeForces platform and its various features.

You can start by brushing up on your basic programming skills. Learn the fundamentals of programming languages like Java, C/C++, Python, and JavaScript. You should also become familiar with basic data structures like arrays, linked lists, stacks, queues, trees, and graphs.

Once you have the basics down, you can begin working on solving problems on CodeForces. It is recommended that you start with the beginner division, which has the easiest problems, to get familiar with the platform and the type of problems it has to offer.

To advance to the higher divisions, you need to have a solid understanding of algorithms and data structures. You should study topics like searching and sorting, dynamic programming, graph algorithms, greedy algorithms, and string algorithms.

Finally, you should work on improving your problem solving skills. You should practice solving practice problems on CodeForces and other platforms, as well as participating in online programming competitions.

Good luck!
