Exercise # 1: Dijkstra's Algorithm (a) Write a function named getShortestPath (graph, from, to) that takes a graph as an input and estimates the shortest distance between a node "from" to a node "to". Example 1: Input Graph: Adjacency list of the following graph. A B 6. 3 10 E D 9 8, F G 10 From: A To: G Output [(A, B), (B, C), (C, G)] That is, the output shows that the shortest path to reach "G" from "A" is through the nodes B and C.
