Question 2 (20 points):
Shadow Moon is recruited by Wednesday to be his body guard, errand boy, and driver while they travel around the United States of America. The purpose? It is all hush hush really. One of the rules of the job Wednesday told Shadow was “no questions”. Despite the secrecy, this job did allow Shadow to visit many cities by accompanying Wednesday around the country. In his notebook, Wednesday took note of which cities he could directly fly to from a given city in case he and Shadow Moon had to disappear quickly. Wednesday’s handwriting is terrible, so Shadow Moon thought storing the travel log digitally would be easier to read. Shadow Moon wants to be able to query a city name and display the cities he can directly fly to from a given city. Unfortunately, Shadow has no idea where to start with this and instead is hoping to recruit you to help him by throwing his travel log at you!
