Consider a grid containing oranges. Each cell in this grid can hold one of three integer values:
The task is to determine the minimum time required for all fresh oranges to become rotten in a grid.
Create a queue to store the rotten oranges and their time of rotting.
Iterate through the grid to find the initial rotten oranges and add them to the queue.
Perform BFS by popping each rotten orange from the queue, rot adjacent fresh oranges, and add them to the queue with updated time.
Continue until the queue is empty, ke...
