BFS vs DFS Explained Clearly
Graphs and trees are non-linear data structures. To process or explore them, traversal algorithms are used. The two most important traversal techniques are: Breadth-First Search (BFS) Depth-First Search (DFS) Both algorithms visit all nodes in a graph or tree, but their strategies and use-cases differ significantly. 1. Breadth-First Search (BFS) Concept Breadth-First Search explores a graph level by level. It visits all neighbors of a node before moving deeper into the graph. ...
