Understanding BFS and DFS Differences (Depth-First Search vs Breadth-First Search)

I revisit LeetCode 841: Keys and Rooms. Instead of solving the problem again, I dive into the methodology behind my original solution. Initially, I thought my approach followed a Breadth-First Search (BFS) strategy. However, as I analyzed it during this video, I realized it was actually Depth-First Search (DFS) all along.

This reflection helped me deeply understand:

-The key differences between DFS and BFS.
-Why using a stack naturally creates a DFS, while a queue results in BFS.
-The nuances of graph traversal techniques and their practical applications.
