"WebWhen an argument to a function is inductively defined, here is a technique for creating a recursive function definition: 1. Specify a value of f(x) for each basis element x in S. 2. For each inductive rule that defines an element x in S in terms of some element y already in S, specify rules in the function that compute f(x) in terms of f(y).
