Shortest Path (DAG) Students, In this coding assignment, you will be asked to write Java code to read a text file (input.txt) of a graph represented as an adjacency list. Example: A, 7, B, 9, C B, 1, C C, 8, E, 2, F D, 1, E, 3, G E, 3, G F, 3, D, -3, H H, 6, G K, 3, H, -1, F The graph represented by the adjacency list above looks like this: The graph is a Directed Acyclic Graph (no cycles). You are required to write Java code to find one correct topological sorting for the graph; and after that, you will ask the user for a node (starting node), then you will print the shortest path from that node to all other (following nodes) Example, after reading the adjacency list above, if the user enters the value 'A' as the starting node, then your program should print the following: B: A - B (7) \\ Essentially, this means that the shortest path from A to B is A - B and its length is 7 C: A - B - C (8) \\ Essentially, this means that the shortest path from A to C is A - B - C and its length is 8 D ... \\ You will have to list all the shortest paths from A to all other nodes E ... F ... ... Your implementation of the topological sort should be efficient

PYTHON ONLY Implement the Dijkstra’s Shortest path algorithm in Python. A graph with 10 nodes (Node 0 to node 9) must be implemented. You are supposed to denote the distance of the edges via an adjacency matrix (You can assume the edge weights are either 0 or a positive value). The adjacency matrix is supposed to be a 2-D array and it is to be inputted to the graph. Remember that the adjacency list denotes the edge values for the...

1. (25) [Single-source shortest-path: algorithm tracing] Show the tracing of Dijkstra's shortest path search algorithm on the weighted directed graph shown below. Do the tracing it twice, first starting with the nodes and, second, starting with the node z. For each tracing, each time the shortest path to a new node is determined, show the graph with the shortest path to the node clearly marked and show inside the node the shortest distance to...
Instructions Write a program in Java that implements the A* algorithm to find a path from any two given nodes. Problem Overview & Algorithm Description In a fully-observable environment where there are both pathable and blocked nodes, an agent must find a good path from their starting node to the goal node. The agent must use the A* algorithm to determine its path. For this program, you must use the Manhattan method for calculating the heuristic. Remember: your heuristic function...

Dijkstra’s Algorithm: You have to implement the Dijkstra’s
algorithm and apply it on the graph provided below.
You have to take the input from the user as an adjacency matrix
representing the graph, the source, the destination. Then you have
to apply the Dijkstra’s algorithm to find the shortest path from
the source and the destination, and find the shortest
route between the source and the destination.
For the input you have to read it from a file. It will...
