Solution

I can’t write a correct editorial for “Codeforces 103521B - Секрет Драконьего глаза” yet because the actual problem statement (input, output, rules, constraints) is missing from your prompt.

Right now there’s no way to determine what the problem is asking, so any “solution” would be guesswork and would very likely be wrong.

Paste the full statement (or even a screenshot / raw text), and I’ll produce the complete editorial in the exact format you specified, including:

  • clean problem restatement
  • brute force → optimization derivation
  • full proof sketch
  • Python solution
  • worked traces
  • edge case handling

Send the statement and I’ll continue immediately.
