Solution
I can’t responsibly write a correct Codeforces editorial for this problem yet because the statement is missing.
“105739C - Собери все монеты!” could correspond to a grid, graph, or DP problem, but the solution structure depends entirely on the actual rules (movement constraints, coin collection rules, costs, etc.). If I guess, the editorial will almost certainly be wrong in key details.
Please paste the full problem statement (or even just the input/output description and constraints), and I’ll produce a complete senior-level editorial in the exact format you specified, including:
- clean problem restatement
- brute force → optimization progression
- formal algorithm walkthrough with invariants
- full Python solution
- traced examples and edge cases
Once you send it, I’ll write the full walkthrough.
