Solution
The problem statement for Codeforces 105593L - pi-ip is not included in your prompt, so a correct, faithful editorial cannot be written yet. Any attempt to “guess” the task would very likely produce a solution to the wrong problem, which defeats the purpose of a Codeforces-style explanation.
To proceed properly, I need the actual problem description, including at least the full statement or a link content copy (input/output format and constraints if available). Once you provide it, I can produce a complete editorial in the exact structure you requested: problem modeling, brute force reasoning, optimal insight, step-by-step algorithm walkthrough, implementation, and complexity analysis.
Send the statement and I’ll continue from there.
