To prove that every element in a recursively defined set S satisfies a certain property
Chapter 5, Problem 6(choose chapter or problem)
Define a set S recursively as follows:I. BASE: a ? S
II. RECURSION: If s ? S, then,
a. sa ? S b. sb ? S
III. RESTRICTION: Nothing is in S other than objects defined in I and II above.
Use structural induction to prove that every string in S begins with an a.
