    Sounds like your are learning recursion and the example you are using is taken from set theory, namely sets and subsets.

    Hint: let your recursion terminate on the empty set.

    if your function
    works on sets, S{},
    recognises the empty set {}, and
    can find subsets from S{}, then
    for every subset Si{} in S{} you can
    call f(Si{}).
