Tools used by gennady korotkevich for programming

I would like to know the programming tools(ide, compiler, debugger) and language used by gennady korotkevich for coding competitions.

Here is the video of him coding in the competitions.

Haven’t seen the video but he uses Far Manager for ide and C++ for programming.

But it is file browsing tool right? How do we customize it for C++ programming?

This is the ide used by Gennady, this is the best tutorial I’ve found for far manager for competitive programming

Don’t even try it right now. Start with some user friendly Ide. Debugging and Writing code on far manager can be time taking for beginners.
