Consider flight network having places of departure and destination. Flight network represent

place name as a node and flight trajectories between palce names are the edges. Consider Pakistan cities as a node and show the source and destination paths, show all the paths separately with their labels and include their code as well.

Example:

Network represents that there are three cities named Karachi, Islamabad and Lahore. Flight schedule from Karachi to Islamabad, Islamabad to Lahore and Lahore to Karchi. Places save as class having departure time and day also.

Note: tree data structure should implement in above Scenario, and Code in java language.

Note: You are not allowed to use any built-in Data Structure classes to implement above scenario.

Plz as soon as possible , I will give you thumbs up
