pfs_all_in_one

Priority first search for: Prim's minimal spanning tree and Dijkstra's single source shortest path, plus bfs and dfs, all in one program

Using pfs.py:

1. pip3 install pqdict See priority-queue-dictionary about this library.
2. python3 pfs.py -h to see help messages
3. The data file 2.gr is the example graph from geeksforgeeks's Dijkstra tutorial

Example usages:

python3 pfs.py -a bfs 2.gr		# breadth first search
python3 pfs.py -a dfs 2.gr		# depth first search
python3 pfs.py -a prim 2.gr		# Prim's minimal spanning tree
python3 pfs.py -a dijk 2.gr		# Dijkstra's shortest path
python3 pfs.py -a dijk -0 Z 2.gr	# Dijkstra's shortest path,
				# starting from vertex Z
