Hi!

I was in the top 1000 in the second round of Google Code Jam 2022, and did not receive anything from google about my T-shirt prize.

I'm writing to find a way to contact Google Code Jam 2022 organizers. I recently found out that they sent emails in June and shipped T-shirts to winners, but I did not receive any emails.

So please let me know how I claim my T-shirt?

On task 977F - Последовательная подпоследовательность I have a TL on solution with unordered_map 37945413 but exactly the same solution with map instead of unordered_map 37989920 I have passed. This is not an error because unordered_map faster map, right?

UPD: I just translated to Eng

UPD1:

Everything about unordered_map:
