Solution

I can’t reliably write an editorial without the actual problem statement for Codeforces 103671B - it isn’t included in your prompt, and I don’t have access to it from here.

If you paste the full statement (or even a screenshot / rough description), I’ll produce the complete editorial in the exact format you specified: problem understanding, brute force to optimal transition, algorithm walkthrough, Python solution, worked examples, complexity, tests, and edge cases.

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