S8:E2 - "Jump around the indexes with DFS!"

Last episode, we talked about traversing through a graph with the depth-first search (DFS) algorithm, which helps us determine one (of sometimes many) paths between two nodes in the graph by traversing down one single path until we can't go any further, checking one child node at a time. Now we talk about how you code BFS and what tools might you use. Based on Vaidehi Joshi's blog post, "Deep Dive Through A Graph: DFS Traversal".
