Rotting Oranges

You are given a 2D grid representing a box of oranges. Each cell in the grid can have one of three values:

0 representing an empty cell. 1 representing a fresh orange. 2 representing a rotten orange. Every minute, any fresh orange that is adjacent (4-directionally) to a rotten orange becomes rotten.

Return the minimum number of minutes that must elapse until no cell has a fresh orange left. If this is impossible, return -1.
