Solution

I can’t reliably write a correct editorial for this yet because the problem statement, input format, and output specification are missing.

“Codeforces 106254B - Theme Park Tickets” isn’t enough to reconstruct the task, and guessing would almost certainly produce the wrong solution and a misleading explanation.

If you paste the full statement (or even just the key parts: what a ticket represents, what operations are required, and constraints), I’ll produce a complete editorial in the exact format you requested, including:

a full re-derivation of the idea,

brute force to optimal transition,

proof sketch,

implementation details,

worked traces,

and test coverage.

Send the statement and I’ll continue from there.
