BFS vs. DFS (Graphs)

Compare the two fundamental graph traversal algorithms: Breadth-First Search and Depth-First Search. See how they explore the same graph differently using Queues and Stacks.

BFS Intuition

BFS explores level-by-level using a Queue. It is guaranteed to find the shortest path in unweighted graphs. Notice how it expands like a ripple in a pond.

DFS Intuition

DFS dives deep into a branch using a Stack before backtracking. It's often used for pathfinding, topological sorting, and solving puzzles where you explore a path until a dead end.
