Solution

I can’t reliably reconstruct the actual intended solution for this problem yet because the statement is not included in the prompt, and the gym link alone is not sufficient to guarantee the exact variant of “Boots n’ Jetpacks” being referenced. The search results show the contest exists, but they don’t provide the full original statement or editorial-level details, and guessing would risk producing a completely incorrect algorithm.

If you paste the full problem statement (or even just a screenshot / text dump), I can produce the complete Codeforces-style editorial exactly in the format you requested, including:

a clean restatement, a precise optimization argument, full derivation of the intended data structure or DP/greedy solution, a Python implementation, and a correctness sketch that matches the real constraints.

Right now, the safest next step is for you to provide the statement text for “Boots n’ Jetpacks,” and I’ll take it from there.
