a. b. For any input string (a), what does the function baz (a) do? You may provide examples to justify your answer (e.g. what does baz ("abcd") return?). If a has length n, what is the recurrence relation of the running time of baz (a)? Assume that appending to a list and string concatenation both run in constant time. (Hint: Determine the number of elements baz (a) returns first.)
