Ruby Collections, Conditional Statements, and Loops

More Ruby programming. Create a git branch for ruby-collections-lesson. Then add the following ruby programs to it.

(1) Write a program which asks for a person's first name, then middle, then last. It should store each of these parts in an array. Finally, it should greet the person using their full name. Call the program full_name.rb.

(2) Write a program called sorted_words.rb. It should prompt the user for words and add each to an array. The user should be able to add as many words as they like, until they just hit enter to return a blank word. Then sort the array using the sort method and print it out.

(3) Write a program with a function add_up(i) . It is to be passed a positive integer, and it will add all the numbers from 1 to that integer and return the sum. Call the function three times within the program, and each time print out the return value. Call the program add_up.rb.

(4) Write a program, leap_year.rb. It will ask the user for a starting year and an ending year, and it will then print out all the leap years between them, including the starting or ending year if those are leap years. The rules for leap years are: A leap year is divisible by 4, except for years that are divisible by 100 -- those aren't leap years -- except for years that are divisible by 400, which ARE leap years.
