Changes 3/28/14

Ruby:

• Wrote a program to explore block functionality in ruby
• It is a bit more complicated than I anticipated and I might split the second nested block into its own variable

• class BlockStorage
    def initialize(&block)
      @block = block
    end
  
    def execBlock(string)
      if @block.respond_to? "call"
        @block.call(string)
      end
    end
  end
  
  bs = BlockStorage.new() do |str|
    arr = str.split(" ").reverse
    arr2 = arr.map do |e|
      puts "#{e}, #{arr.first}, #{arr.last}"
      if e == arr.first
        e.gsub(/\W$/, '').capitalize
      elsif e == arr.last
        e.downcase
      else
        e
      end
    end
    arr2.join(" ")
  end
  
  puts bs.execBlock("Block coding is pretty darn cool.")

  # Outputs  'Cool darn pretty is coding block'

  puts bs.execBlock("It really streamlines the process.") 

  # Outputs 'Process the streamlines really it'
