Question
Exercise # 2: Modify getShortestPath (graph, from, to) function so that if there is more than
one minimum path from source node to destination node, it gives you the one with the minimum
number of edges.
Example 1:
Input
Graph: Adjacency list of the following graph.
6.
4
From: A
To: For B
[(A, F)]
That is, the distance from A to Fis 10 both through the following path
A>D>F,
AD>c>G>F
Output
the correct answer is AD>F
((A, B)
That is, the distance from A to B is 7 both through the following paths
A>B,
AD>c>B
the correct answer is AB
