Solution: Implement Breadth-First Search
Understand how to implement breadth-first search (BFS) on a directed graph starting from a source vertex. This lesson guides you through using queues and visited arrays to ensure all reachable vertices are traversed in order while avoiding cycles. You will gain practical insight into BFS traversal and its computational complexity relevant to coding interviews.

Statement
Given a directed graph represented as an adjacency list, graph, and an integer, source, which is the starting vertex number, return an array of integers, result, that contains the order of the graph’s breadth-first traversal starting from the source vertex.
