Subject: Would this be possible?

Would this work to find the mean average and the number of elements 
greater than the average?



# Calculating Avg and # of elements greater than Avg. in Ruby

sum = 0.0
n = 0
count = 0

while figure = STDIN.gets.to_f
    sum += figure
    n += 1
end

average = sum / n
puts "Average = #{average}"

while figure = STDIN.gets.to_f
     if figure > average
          count +=1
     end
end

puts “Number of elements greater than Avg = #{count}”
