Reformat/Refactor a Golfer Class

A simple case of removing unneeded code and fixing broken indentation.

Input

class Golfer
     def initialize; end # initialize
  def useless; end;
  
     def self.hello(a,b,c,d)
      puts "Hello #{a}, #{b}, #{c}, #{d}"
   end
end

Output

class Golfer
  def self.hello(*a)
    puts "Hello #{a.join(',')}"
  end
end
