What is a breadth-first search algorithm?

A breadth-first search (BFS) algorithm is used to search tree or graph data structures. It starts from the root node, proceeds through neighbouring nodes, and finally moves towards the next level of nodes. Till the arrangement is found and created, it produces one tree at any given moment. As this pursuit is capable of being executed by utilising the FIFO (first-in, first-out) data structure, this strategy gives the shortest path to the solution.
