Hello Codeforces!
Today, MikeMirzayanov taught me how to add contests to the Gym, so we've started adding old Google Code Jam rounds. We think it's a good idea to create a comprehensive (or almost comprehensive) archive of all GCJ rounds in the Gym.
I've added 2015 Google Code Jam Round 1A (GCJ 15 Round 1A) and 2015 Google Code Jam Round 1C (GCJ 15 Round 1C) today.
While Google's archives don't include solutions, we did find a user-generated archive at https://github.com/kamyu104/GoogleCodeJam-2015. However, it would be great to have additional sources for verification.
Would any of you be able to help us find other reliable sources for correct solutions? This way, we can be absolutely sure that all the information is accurate.
Thank you!
