Throughout, a graph is given as input as an adjacency list. That is, G is a dictionary where the keys
are vertices, and for a vertex v,
G[v] = [u such that there is an edge going from v to u].
In the case that G is undirected, for every edge u − v, v is in G[u] and u is in G[v]

Question :  Write the full pseudocode for BFS.
Input: An undirected connected graph G, and a vertex v.
Output: Visit every node of the graph using BFS, and output distance of every vertex from v.
