Q: In Ruby, the max method returns the largest number in an array of integers. Ex:
    [14, 23, 6, 9, 54, 10].max #=> 54
Write an implementation of the max method that accepts an array as it's argument. Do not use the existing .max method

class Testing
  puts "enter five number to check the greatest among from that." 
  a = gets.chomp 
  b = gets.chomp 
  c = gets.chomp 
  d = gets.chomp 
  e = gets.chomp
  array = [] 
  array << a.to_i 
  array << b.to_i 
  array << c.to_i 
  array << d.to_i 
  array << e.to_i
  def self.message(arr) 
    arr.sort.last 
  end 
  puts "the greatest number among the entered number is " + "#{message(array)	}"
end
