None of the above
Answers
Answer:
begining from the node,all adjacent
Answer:
[A]. All of the surrounding nodes are travelled through initially after starting at a node.
Explanation:
The BFS method is used to find node in a data structure of trees that meet a predetermined criteria. It starts at the beginning of the tree and analyzes each node there just before passing on to the node at the subsequent depth level. To maintain track of the child nodes that were discovered but haven't been fully investigated, more memory, typically a queue, is required.
A technique called breadth first traversal (BFS) traverses all descendants of a visiting node before any descendants of those descendants. An algorithm for exploring a tree or an unordered graph data structure is called breadth-first search (BFS). Here, we begin with a node, visit all of its neighbours on the same level, and then continue on to its neighbouring successor node on the following level.
BFS is a traversal algorithm that requires you to explore neighbour nodes by traversal the graph layer-by-layer beginning from a chosen node (source or starting node) (nodes which are directly connected to source node). Then, you must go in the direction of the nodes in the network on the following level.
