maybe
----------------------------------------------
fib = Hash.new{|h,k| h[k] = h[k-2] + h[k-1]}
fib[0], fib[1] = 0, 1

print "Enter a number: "

i = gets.to_i

puts "The #{i} Fibonacci number is #{fib[i]}"
puts (0..i).map{|k| fib[k]}.join(' ')
----------------------------------------------

cheers
