LeetCode 75 C++ | Step-by-Step Solutions (LAN Academy) - When Will All Oranges Rot? 🍊 LeetCode 994 Explained Step-by-Step (C++)

🍊 LeetCode 994 – Rotting Oranges In this video, we solve the Rotting Oranges problem step-by-step using Breadth-First Search (BFS) in C++. Problem summary: You are given an m x n grid representing oranges: 0 → empty cell 1 → fresh orange 2 → rotten orange Every minute, fresh oranges adjacent to a rotten one (up, down, left, right) become rotten. We need to return the minimum number of minutes required until there are no fresh oranges left — or -1 if that’s impossible. 🎯 Concepts covered: Breadth-First Search (BFS) traversal Multi-source BFS (starting from all rotten oranges at once) Queue-based simulation Grid traversal patterns in C++ 💻 Time Complexity: O(m × n) 💻 Space Complexity: O(m × n) 🎥 Watch next: 👉 Binary Tree – BFS Explained Clearly (LAN Academy Playlist) #leetcode #cplusplus #bfs #rotatingoranges #lanacademy #codinginterview #programming
