WebApr 2, 2024 · Breadth-First Search is a graph traversal algorithm that explores all the vertices of a graph in breadth-first order. This means that BFS visits all the neighbors of a vertex before exploring the neighbors of the neighbors. In other words, BFS traverses the graph in layers, starting from the source vertex and moving outwards. ... WebJan 17, 2024 · 2.

It is a collection of nodes that are connected by edges and has a hierarchical relationship between the nodes. The topmost node of the tree is called the root, and the nodes below it are called the child nodes.
