wordSort.sort! 

=begin 
Conditional is performed on the array: if array index is equal to zero or has 
a remainder of zero after being divided by 2 then call upcase method on element. 
Else call lowercase method on that index number. 
=end

puts "Here are the words you entered:" 

puts wordSort 

Answer 1

enum = [:upcase, :downcase].cycle 
    #=> #<Enumerator: [:upcase, :downcase]:cycle> 
"Here are the words you entered:".gsub(/\w+/) { |x| x.send enum.next } 
    #=> "HERE are THE words YOU entered:"
