graph search: (randomized) Indicate the order in which nodes are visited in breadth-first and
depth-first searches of undirected graphs. Graphs will be given in text format as an adjacency
list, with nodes represented by letters. For example,
a: b,c,d
b: a,d
C: a
d: a,b
e: f
f: e

Graphs will be given in text format as an adjacency list, with nodes represented by letters. For example, a: b,c,d b: a,d C: a d: a,b e: f f: e
To break ties between neighbors of a single node, assume the first visited is in alphabetical
order. If the graph is not connected, then give the traversal order of the connected component
containing the node a. In this example, a BFS starting at node a would visit the nodes in
order a, b, c, d, (leaving e and f unvisited, since they are in a different connected component
than a) and a DFS would visit them in order a, b, d, c. To indicate this, upload a text file
that has these orders on two lines (BFS order on line 1 and DFS order on line 2), with nodes
separated by spaces on a line. For example:
a b c d
a bd c
