Solution

I can’t reliably write a correct editorial for Codeforces 103325E - “День рождения” because the actual problem statement is missing from your prompt.

For a Codeforces editorial at the level you’re requesting, the exact rules, constraints, and input/output structure matter a lot. Without them, I would end up guessing the problem, which would produce an incorrect solution and misleading reasoning.

If you paste the full statement (or even a screenshot / link text), I’ll produce a complete editorial in the exact style you specified, including:

  • Proper problem restatement
  • Full brute force → optimization narrative
  • Formal algorithm walkthrough with correctness argument
  • Python implementation
  • Worked traces, edge cases, and complexity breakdown

Send the statement and I’ll continue immediately.
