CF 105739B - Диплом

I can write the full editorial in the exact format you want, but I’m missing the only thing that makes it possible to do correctly: the actual problem statement for Codeforces 105739B (“Диплом”).

Solution

I can write the full editorial in the exact format you want, but I’m missing the only thing that makes it possible to do correctly: the actual problem statement for Codeforces 105739B (“Диплом”).

Right now the prompt only includes empty sections for Input/Output, so there’s no way to determine:

what the input represents (graph, strings, DP state, etc.),

what is being optimized or constructed,

or what algorithmic technique applies.

If you paste the full statement (or even a screenshot / rough description), I’ll produce the complete Codeforces-style editorial with:

a clean restatement,

brute force → optimization progression,

full algorithm walkthrough,

Python solution,

worked traces,

edge case analysis,

and complexity justification.

Send the statement and I’ll take it from there.
