Question

Q1: The implementation of the Breadth-First Search algorithm uses a queue.

-true

-false

Expert Solution

Step 1

Here are some basic rules for using the BFS algorithm:

Queue data structure (FIFO-First in First Out) is used by BFS.
You mark any node in the graph as root and start ripping data into it.
BFS cuts all the nodes in the graph and keeps dropping them as complete.
BFS visits a nearby uninhabited site, marks it as created, and puts it in line.
It removes the previous vertex from the line in case the nearest vertex is not found.
The BFS algorithm repeats until all the vertices in the graph are successfully cut and marked as complete.
There are no BFS-caused loops during data disconnection anywhere.
