WebBreadth-First Search is a recursive method for searching all the nodes of a tree or graph. In Python, We can utilize data structures like lists or tuples to perform BFS. In trees and graphs, the breadth-first search is virtually identical. The only distinction is that the tree might have loops, which would enable us to revisit the same node.
