🚀 Graph Tutorial 17: Surrounded Regions | Replace O's with X's | BFS & DFS | Leetcode | Java | Graph

#interviewWithBunny #graph #graphtutorial Are you struggling with the LeetCode "Surrounded Regions" problem? In this comprehensive tutorial, I break down both BFS and DFS approaches to solve this classic boundary traversal challenge Problem: https://leetcode.com/problems/surrounded-regions/ This video walks you through: ✅ The core intuition behind the "Surrounded Regions" problem ✅ Step-by-step implementation of the DFS solution ✅ Visual explanations of how the algorithms work on the board I explain why we need to start from the boundary cells and work our way inward, rather than checking each cell individually. You'll understand how to identify "safe" regions that shouldn't be flipped, and how to efficiently mark and process the board. ►►Playlist: Graph Tutorial 1: Introduction to Graph | Types | Terminologies: https://youtu.be/yF-n_vjhoAw Graph Tutorial 2: Representation of Graph in Java | Which one is Best : https://youtu.be/cseN3bt_Vhw Graph Tutorial 3: Graph Simplified Implementation in Java: https://youtu.be/psNSeh15jJ8 Graph Tutorial 4 : Breadth First Search (BFS) | Traversal Technique: https://youtu.be/Z4plqYyalBQ Graph Tutorial 5 : Depth First Search (DFS) | Traversal Technique: https://youtu.be/RNKPWjmyTe4 Graph Tutorial 6: BFS & DFS Traversal For Disconnected Graph: https://youtu.be/IWc2NU1yrik Graph Tutorial 7: Number of Provinces | Connected Components: https://youtu.be/tvOrIT2fBT8 Graph Tutorial 8: Number of Islands | Count Connected Components in Matrix: https://youtu.be/dX6RZYxw41E Graph Tutorial 9: Rotten Oranges Leetcode: https://youtu.be/nt-rCF_D0iI Graph Tutorial 10: Detect a Cycle in an Undirected Graph using BFS: https://youtu.be/p69HDt9XNlE Graph tutorial 11: Detect a Cycle in an Undirected Graph using DFS: https://youtu.be/Y8bOGiLkBqg Graph Tutorial 12 : Detect Cycle in a Directed Graph using DFS : https://youtu.be/Exvy4GvTets Graph Tutorial 13: What is Topological Sorting: https://youtu.be/-LFvAXxcxTQ Graph Tutorial 14: Topological Sort Algorithm using DFS Traversal: https://youtu.be/ldsh1gHm4qo Graph Tutorial 15: Kahn's Algorithm: https://youtu.be/Fmcy7CbwSIg Graph Tutorial 16: Course Schedule I and II : https://youtu.be/Q6pP5Bf6QzM Graph Tutorial 17: Surrounded Regions: https://youtu.be/aUt6pYAZhx8 If you found this tutorial helpful, please LIKE, COMMENT, and SUBSCRIBE for more in-depth tutorials on LeetCode problems, graph algorithms, and coding interview preparation!
