### Questions

Any more hints on problem 2?
  : "Trust the magic recursion fairy."  You've determined that `lst`
    is a pair.  You tally the rest with `(nested-list-tall (cdr lst) pred?)`.
    What do you do next?

Any hints on problem 4?
  : Use the debugger.
  : Run it "by hand"

Can I have a more comprehensive test suite for problem 4?
  : Sure.

```
(check-equal? (next-larger 1/2 (vector 1 2 3 4 5 6)) 1)
(check-equal? (next-larger 1 (vector 1 2 3 4 5 6)) 2)
(check-equal? (next-larger 3/2 (vector 1 2 3 4 5 6)) 2)
(check-equal? (next-larger 2 (vector 1 2 3 4 5 6)) 3)
(check-equal? (next-larger 5/2 (vector 1 2 3 4 5 6)) 3)
(check-equal? (next-larger 3 (vector 1 2 3 4 5 6)) 4)
(check-equal? (next-larger 7/2 (vector 1 2 3 4 5 6)) 4)
(check-equal? (next-larger 4 (vector 1 2 3 4 5 6)) 5)
(check-equal? (next-larger 9/2 (vector 1 2 3 4 5 6)) 5)
(check-equal? (next-larger 5 (vector 1 2 3 4 5 6)) 6)
(check-equal? (next-larger 11/2 (vector 1 2 3 4 5 6)) 6)
(check-equal? (next-larger 6 (vector 1 2 3 4 5 6)) #f)
(check-equal? (next-larger 13/2 (vector 1 2 3 4 5 6)) #f)
```

Can't you write something more concise?
  : Yes.  But I thought this was clearer.

Since #4 can return false, do we have to switch to the hideous/wonderful and/or format?
  : No.
