🚀 LeetCode 2812 | Find the Safest Path in a Grid | Multi-Source BFS + Binary Search + BFS | C++

In this video, we solve LeetCode 2812 - Find the Safest Path in a Grid using an Optimal Graph Algorithm. We first calculate the minimum distance of every cell from the nearest thief using Multi-Source BFS, and then apply Binary Search on the answer combined with BFS to determine the maximum safeness factor. This is one of the most important interview problems because it combines multiple graph concepts into a single solution. 📚 What You'll Learn ✅ Problem Explanation ✅ Brute Force Idea ✅ Why Brute Force Fails ✅ Multi-Source BFS ✅ Binary Search on Answer ✅ BFS Validation ✅ Complete C++ Implementation ✅ Time & Space Complexity Analysis ✅ Dry Run with Example ⏱️ Timeline 00:00 Introduction 00:28 Understanding the Problem 02:25 Calculate Distance 05:36 Intuition for Bfs and Priority Queue 08:10 Complete C++ Code 14:10 Complexity Analysis 💻 Code 🔹 GitHub (C++ Solution) https://github.com/zorocodezz-coder/L... 🔗 Problem Link LeetCode: https://leetcode.com/problems/find-th... 🧠 Concepts Covered Graphs Breadth First Search (BFS) Multi-Source BFS Binary Search on Answer Matrix Traversal Shortest Distance Path Finding Interview Preparation Competitive Programming 📈 Time Complexity Multi-Source BFS: O(n²) Binary Search: O(log n) BFS Check: O(n²) Overall: O(n² log n) Space Complexity: O(n²) 🎯 Playlist 📌 LeetCode Daily Solutions (C++) 📌 Graph Algorithms 📌 Binary Search Problems 📌 BFS & DFS Mastery 👍 If you enjoyed this video ✅ Like the video ✅ Subscribe for daily LeetCode solutions ✅ Share it with your coding friends ✅ Comment your approach or doubts #️⃣ Hashtags #leetcode #leetcode2812 #graphs #bfs #multisourcebfs #binarysearch #cpp #dsa #codinginterview #competitiveprogramming #algorithms #programming #codehunt 🔍 SEO Keywords LeetCode 2812 Find the Safest Path in a Grid LeetCode 2812 C++ Find the Safest Path in a Grid Solution Multi Source BFS Binary Search on Answer Graph Problems BFS Grid Problems Shortest Distance Grid LeetCode Graph Problems Coding Interview Questions DSA C++ Competitive Programming Code Hunt
