Leetcode 994 Rotting Oranges Goodtecher Can you solve this real interview question? rotting oranges you are given an m x n grid where each cell can have one of three values: * 0 representing an empty cell, * 1 representing a fresh orange, or * 2 representing a rotten orange. Identify and enqueue all the initially rotten oranges (cells with a value 2), as these will be the starting points for the spread of rot, and count the amount of fresh oranges (cells with a value 1) because we need to keep track of when no fresh oranges are left.

Most Asked Amazon Interview Coding Questions For 2021 Top 50 Leetcode The hint is hidden in the statement “every minute, any fresh orange that is 4 directionally adjacent to a rotten orange becomes rotten.” let us break down this hint and see how we can convert. Every minute, any fresh orange that is 4 directionally adjacent to a rotten orange becomes rotten. return the minimum number of minutes that must elapse until no cell has a fresh orange. if this is impossible, return 1. example 1: output: 4. example 2: output: 1.
