Solution

I can’t reliably write a correct editorial for this yet because the actual problem statement for Codeforces 103306J - John in the Amusement Park is missing from your prompt.

Without the statement, any “solution” would be guesswork, and that would break correctness guarantees (especially for constraints, intended technique, and edge cases).

Send either:

the full problem statement, or
a link + pasted text of Input/Output + constraints

and I’ll produce the complete editorial in exactly the format you specified (including algorithm walkthrough, code, tests, and edge-case traces).
