Question

I am trying to subtract two values in my array the largest and the smallest. I have sorted them then tried to subtract them but the output is different. I am also trying to use a loop but I keep getting errors. It would be nice to show me what I am doing wrong. thanks

numbers = [randomNo = rand(50),randomNo = rand(50),randomNo = rand(50),randomNo = rand(50)]

loop do  
puts "type s to start and q to quit"
input = STDIN.gets
break if input == q
puts numbers.sort.inspect 
puts numbers.first - numbers.last
end   

output:[3, 13, 21, 46] 
18

I wanted 46 – 3

Answer 1

What about this instead?

numbers = Array.new(10) {|n| rand(50) }
result = numbers.max - numbers.min
puts result
