📜 WAYPOINT LESSON
Final Simulation — Full Contest Stack
⭐⭐⭐ advanced⏳ 60 min read📍 Lesson 277 of 281
Run a complete single-problem simulation: read, plan, implement, self-review, submit — and if it fails, debug like it's a real contest.
Mô phỏng cuối — Chuẩn Vòng Thi Đầy Đủ. Run this as one sitting: read, plan on paper, implement, self-review the boundary cases, then submit. The problem is deliberately mild in algorithm (grid DP) but heavy in reading discipline — blocked-cell bookkeeping is where timed simulations die. If your first submission fails, treat it as a contest: do not guess-fix; write down the failing behavior first.
