Huge thanks to JetBrains for the Kotlin contest! I ended up placing 47th and still scored a branded T-shirt, which is pretty awesome. Really appreciate everything JetBrains does for the Kotlin community.
you very clearly cheated. https://mirror.codeforces.com/contest/2087/submission/314389940
very disappointing that cheaters are receiving rewards.
organizers please look into this BledDest
Algebrant is banned. Is this because it cheated?

Do you send T-shirts in Russia?
The T-shirt is absolutely wonderful, I won it in the last contest. The fabric and the prints are excellent.

I've also sent DMs to JetBrains and BledDest but I haven’t gotten any reply.
This really isn't about the t-shirts anymore. I’m just curious how far this will go because honestly I can’t afford to buy my own clothes and I was hoping for a Kotlin collectible at least. It feels like I’m begging at this point.
I won that back when I was in high school. Now I’m in college. Please give a response.
How do we get the update for the tshirt?
I have submitted the details before the deadline but no updates since.
same here ... wanted to know whats the further process
Are there any updates on the t-shirt distribution? Haven't got any email regarding this.
Is the prize being mailed?
Man, who thought that blue color for a t-shirt would be a good idea??? Even black color would have been better!
