Question $7$

What does this recursive program return in terms of the parameter variable, $n?$

public int foo$($int n$)\{$

if $)(1$

return $1$ ;

else

return $n*$ foo$($n$-1)$;

$\}$

It returns the value $n(n-1)(n-2)dots(3)(2)(1)$

It returns the value $n$

It returns the value $n^{**}(n-1)$

It always returns $1$
