Water Bottles (LeetCode 1518) — Step-by-Step Exchange Simulation | Animated

Описание: LeetCode 1518 – Water Bottles solved with an animated, recursive simulation using my custom Visualizer. We model the exact exchange process (full → consumed → empties → new full) and prove correctness with a clear dry run and edge cases. No “greedy” shortcuts—just the true recurrence you’d write in code.


What you’ll learn
• Exchange simulation explained visually (how empties become new bottles)
• The recursion step: consumed + consume(next_full)
• Handling base case:
• Edge cases (large counts, tight exchanges, off-by-one traps)
• Time/space complexity and an iterative equivalent
