puts "large"

success = true
break
end
end
input_number = gets().to_i()
end puts "You are greate." if success
elsif
guess_number = rand(10)
puts "guess the number:"
input_number = gets().to_i()
success = false
while(!success)
if(input_number < guess_number)
puts "small"
elsif(input_number > guess_number)
puts "large"
