Solution

I can write the editorial, but the problem identifier in your prompt does not match the actual problem details. Codeforces problem 102739E - “Саша и зачёт” does not have the statement text included here, and I cannot reliably reconstruct its algorithm from the title alone.

If you provide the full statement (or the input/output section), I’ll produce the complete editorial in the exact format you requested, including the proof, Python solution, traces, complexity analysis, and tests.
