DIY: Rotting Oranges

Learn to solve the rotting oranges problem using Kotlin by modeling the grid as a network and applying propagation techniques. Understand how to calculate time until all fresh oranges decay or identify impossible scenarios. This lesson sharpens your skills in network traversal and real-world problem mapping for coding interviews.

Problem Statement

You are given an m * n grid. Each cell in the grid contains one of the three values: [0, 1, 2]. Each value represents the following:

  • 0 represents an empty cell.
  • 1 represents a fresh orange.
