- Capital OneMediumSoftware EngineerGrid State After a Given Number of Days of Spoilage Spreading to Neighbors
A grid holds empty cells, fresh items and spoiled items, and each day spoilage spreads from every spoiled item to its edge-adjacent fresh neighbors. Given the grid and a number of days that may be very large, return the grid after exactly that many days. It tests simultaneous multi-source spreading, day-by-day timing, and unreachable cells.
