Suppose the following function foo was called with a list of size 8. How many operations on the handler stack (push or pop) would result during the execution of the function? def foo(L): try: if len(L) 0: == return 0 else: # convert L[0] to int s = int (L[0]) # call foo w/ rest (L) r = foo (L[1:]) return s + r except ValueError: return 0 10 18 16 2 Suppose the following Scheme expression was evaluated. How many times would function foo be called? (call/cc (lambda (c) (define cont #f) (call/cc (lambda (c) (set! cont c) (foo) (cont foo) 1 infinity
