Breadth First Search (BFS) Tutorial - InterviewBit
Detailed Tutorial on Breadth First Search (BFS), an algorithm for traversing or searching layerwise in tree or graph data structures. Check out our curated list of practice problems and interview questions to improve your understanding of the topic.
Breadth First Search (BFS) is a traversing algorithm where we start at the tree root (or any arbitrary node of a graph called ‘source node’), and investigate all of the neighboring nodes (directly connected to source node) at the present level before moving on to the nodes at the next level. The process is repeated until the desired result is obtained.
