Task B: Airports Management Implement a Windows Forms Application (.NET framework) in C# (with a GUI) which allows users to: Insert an airport by using its code (assume the airport code is a string, see Figure 1 below) - Insert/Remove a direct connection (i.e., direct flight) between two airports given their codes (see Figure 1 below) - Display the codes of the airports that can be reached from a starting airport by either using direct or connecting flights. In this case, allow the user to insert the starting airport and specify if interested in only direct or both direct and connecting) types of flights. In your screencast, test the application on the airports shown in Figure 1 (below). Hints to complete the task: To implement the application you will need to use and adapt the classes and the methods) of Graph and Graph Node seen in the lecture/lab to be able to store the code of the airports (string) as ID of the nodes. To implement the removal of an edge, check how we did the addition of an edge. For the last point ("Display the codes of the airports that can be reached...") use the idea of graph traversal. Start from the starting code for the DFS that you can find on the lab slides (remember that in this task the ID of a node is a string). The method to implement the DFS needs to be in the class Graph. On the GUI you may use a checkbox to allow the user to specify if interested in only direct or both (direct and connecting) types of flights. of graph traversal.

A direct connection (i.e., direct flight) between the two airports is denoted by a directed edge. e.g., there is a direct flight going from cdg to lis, but there is no direct flight going from lis to cdg. Airport codes (cgd, lis, etc..) are strings. Starting from lux (i.e., starting airport) one can reach (by using direct or connecting flights): ams, cdg, lis. On the other hand, starting from lux (i.e., starting airport) one can reach (by using only direct flights): ams
