CF 105905E - Стоимость игровой сессии

I can’t reliably write a correct editorial yet because the actual problem statement for Codeforces 105905E - “Стоимость игровой сессии” is missing from your prompt, and it’s not available in the context I currently have.

Solution

I can’t reliably write a correct editorial yet because the actual problem statement for Codeforces 105905E - “Стоимость игровой сессии” is missing from your prompt, and it’s not available in the context I currently have. Without the statement, any “solution” would be a guess, and that would break correctness in a way that’s especially dangerous for an editorial.

If you paste the full statement (or even just input/output + constraints), I’ll immediately produce the full Codeforces-style editorial exactly in the format you requested.

To make it easy, you can send any of:

  • full problem text in Russian or English
  • a screenshot
  • or just the key parts: what defines a “game session cost” and what needs to be computed

Once I have that, I’ll reconstruct the intended solution and write the complete editorial with proof, walkthrough, code, and edge cases.
