Laurent_R:

Yeah, I know. I used the recursive method on purpose just 'cause it was easy and I was demonstrating recursion to a beginner. (If I recall correctly, I used the fibonacci series because it was even uglier than the traditional factorial example of recursion.) If I was actually interested in the fibonacci numbers (I don't recall actually ever needing them for anything), I'd've just created them in a loop, something like:

my @vals = (1, 1);

 . . .

sub fibo {
    my $num = (shift)-1;
    while ($#vals < $num) {
        push @vals, $vals[-1] + $vals[-2];
    }
    return $vals[$num];
}
