I recently ended up my career as an eligible ICPC contestant. I realized that I have participated in a lot of codeforces's Gym contests in order to train for ICPC contests.
At the beginning of training in the Gym, neither me or my teammates were able to see the submissions for problems we hadn't solve yet. I remember it was difficult to find editorials for some of the contests present in the Gym also. So, here is a repository (https://github.com/albexl/codeforces-gym-submissions) with all the contests that I (together with my teammates) participated in.
For those who want to consult some solution and still have no gym privileges feel free to use it.
I suppose there should be other ways to see submissions from the Gym. But I'm happy that I can, at least, give one extra alternative.
