Solution

I don’t have the actual statement of Codeforces 103115G - “cocktail with snake”, so I can’t reliably reconstruct the problem, constraints, or intended solution path.

Right now anything I write would be guesswork, and for an editorial that would completely break correctness.

If you paste the problem statement (or even just the core description + constraints + samples), I’ll produce a full Codeforces-style editorial in the exact format you requested, including:

clean restatement of the problem
brute force → optimization progression
full correctness reasoning
Python solution
worked traces
edge case analysis and tests

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