Problem Statement

Write a program that accepts a name as input and outputs the lyrics to the Shirley Ellis song "The Name Game".

The regular verse Unless your name begins with a vowel (A, E, I, O, U), 'B', 'F' or 'M' you don't have to care about special rules. The verse for the name 'Gary' would be like this: At the end of every line, the name gets repeated without the first letter: Gary becomes ary If we take (X) as the full name (Gary) and (Y) as the name without the first letter (ary) the verse would look like this: Vowel as first letter of the name If you have a vowel as the first letter of your name (e.g. Earl) you do not truncate the name. The verse looks like this: 'B', 'F' or 'M' as first letter of the name In case of a 'B', an 'F' or an 'M' (e.g. Billy, Felix, Mary) there is a special rule. The line which would 'rebuild' the name (e.g. bo-billy) is sung without the first letter of the name. The verse for the name Billy looks like this: For the name 'Felix', this would be right:

Let's start with the solution:

import "/str" for Str

var printVerse = Fn.new { |name|
    var x = Str.capitalize(Str.lower(name))
    var z = x[0]
    var y = "AEIOU".contains(z) ? Str.lower(x) : x[1..-1]
    var b = "b%(y)"
    var f = "f%(y)"
    var m = "m%(y)"
    if (z == "B") {
        b = y
    } else if (z == "F") {
        f = y
    } else if (z == "M") {
        m = y
    }
    System.print("%(x), %(x), bo-%(b)")
    System.print("Banana-fana fo-%(f)")
    System.print("Fee-fi-mo-%(m)")
    System.print("%(x)!\n")
}

["Gary", "Earl", "Billy", "Felix", "Mary", "Steve"].each { |name| printVerse.call(name) }
