Challenge: Implement breadth-first search
Learn to implement the breadth-first search algorithm by completing the doBFS() function. Understand how to track distances and predecessors for each vertex to map shortest paths from a source in graph traversal.

Implement BFS
In this step, you'll finish implementing the doBFS() function, which performs a breadth-first search on a graph and returns an array of objects describing each vertex.
For each vertex
