As for the contest, I couldn't get the prize. I couldn't solve the second problem for about 8 hours, I always failed the last test. I generated about 60 of my own tests to find holes in my solution, but it still didn't work. Then someone gave me a hint that I should have pulled the 2025 check from recive to init and only then I was able to pass the second problem. With other problems, the problem was basically the same. I couldn't complete the last tests and stopped solving the contest.
Now I'm fixing the agent so that it can solve problems better
