Problem 1: Rolodex (Note: A Rolodex is a Contact List) Write a program that manages a rolodex. This program prompts the user for the name of a rol file. This program should be able to load any rol file and require that the file extension -i.e the last 4 letters of the file be rol. The file rol is consider a valid file. If the file exists the program loads in the contacts stored in the file. A Rolodex contains unique individuals, no duplicate names are allowed. However, name lookups are case sensitive, so \"Apple\" and \"apple\" are considered different names allowed However, nameSolution
