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?

As-salamu alaykum, Codeforces! (Peace, Codeforces!)

I am glad to invite you to HackerEarth September DSA Contest. The contest is rated and will start 11 September at 10:00 AM BDT. In contest will be given 3 problems to solve in 90 minutes. All the problems are prepared by me, and I hope that you will like them.

Meme:

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:
