What is the right structure? You want to store a bunch of colors so you can later choose one at random. Batting order of a baseball team. Students names and their grades on a project. Friends names and their phone numbers Height, width and location of a sports field. Movies a person has watched. Items in a shopping cart. A student's grades.

What is the right structure? The grades for all students in a class All books in a store arranged by category Many recipes each containing many steps Phone numbers that have been called this month on a phone plan divided by area and country code for billing simplicity

Exercise Write a program that allows a user to ask the distance between two friends. If person 1 and person 2 are friends then they are distance 0 If person 2 is friends with a friend of person 2 they are distance 1 What structure is appropriate for this problem?
