unique please Your task for this assignment is to identify a spanning tree in one connected undirected weighted graph using C++. Implement a spanning tree algorithm using C++. A spanning tree is a subset of the edges of a connected undirected weighted graph that connects all the vertices together, without any cycles. The program is interactive. Graph edges with respective weights (i.e., v1 v2 w) are entered at the command line and results are displayed on the console. Each input transaction represents an undirected edge of a connected weighted graph. The edge consists of two unequal non-negative integers in the range 0 to 9 representing graph vertices that the edge connects. Each edge has an assigned weight. The edge weight is a positive integer in the range 1 to 99. The three integers on each input transaction are separated by space. An input transaction containing the string “end-of-file” signals the end of the graph edge input. After the edge information is read, the process…
Solve by Jaa 11.10 (Implement Mystack using inheritance) In Listing 11.10, flyStack is imple- mented using composition. Define a new stack class that extends Arraylist. Draw the UML diagram for the classes then implement MyStack. Write a test pro- gram that prompts the user to enter five strings and displays them in reverse order.
Array lists and linked lists are both examples of list implementations. Give an example of a case in which an array list might be preferable over a linked list. Justify your actions in each scenario.
Define the abstract base class LinkedSQD_Base using a linked implementation. Indicate whether each field and method should be public, protected, or private, and explain why. Implement each of the ADTs stack, queue, and deque as a class that extends your base class.

Your task for this assignment is to identify a spanning tree in a connected undirected weighted graph using C++. 1. 2. 3. 4. Implement a spanning tree algorithm using C++. A spanning tree is an acyclic spanning subgraph of the of a connected undirected weighted graph. Your program will be interactive. Graph edges with respective weights (i.e., v1 v2 w) are entered at the command line and results are displayed on the console. Each input transaction represents an undirected edge of a connected weighted graph. The edge consists of two unequal uppercase letters representing graph vertices that the edge connects. Each edge has an assigned weight. The edge weight is a positive integer in the range 1 to 99. The three values on each input transaction are separated by a single space. An input transaction containing the string “end-of-file" signals the end of the graph edge input. After the edge information is read, the spanning tree evaluation process begins. Use an adjacency matrix for…
For a weighted graph, each edge is an instance of WeightedEdge. a. WeightedEdge is an interface that must be implemented differently depending on the data type of the weights on the edges. b. WeightedEdge is a subtype of Edge. c. WeightedEdge implements the Edge interface. d. WeightedEdge is a subclass of AbstractEdge.
