Solution

The problem statement section is empty, so there’s no way to reconstruct the actual task reliably.

For a Codeforces editorial, the difference between a graph problem, a data structure problem, or a combinatorics problem completely changes the approach, so guessing would almost certainly produce a wrong solution and a misleading explanation.

Paste the full statement (or at least the input/output format and constraints), and I’ll write the complete editorial in the exact style you requested.
