As a practice to learn ruby I tried to create a recursive program

(Fibonacci sequence), as a step up from "hello world", but I get a stack

level too deap error, any ideas what I am doing wrong?

## ···

-----------------

def fib ( n )

if n == 0

return 0

elseif n == 1

return 1

else

return fib(n-1) + fib(n-2)

end

end

0.upto(30) { |i| puts "The #{i} Fibonacci number is #{fib(i)}"

}

--------------

ruby test.rb

The 0 Fibonacci number is 0

test.rb:7:in `fib': stack level too deep (SystemStackError)

from test.rb:7:in `fib'

from test.rb:7:in `fib'

from test.rb:11
