Do a to e as in Exercise 6 for the water jugs problem:

There are two jugs, one holding 3 and the other 5 gallons of water. A number of things can be done with the jugs: they can be filled, emptied, and dumped one into the other either until the poured-into jug is full or until the poured-out-of jug is empty. Devise a sequence of actions that will produce 4 gallons of water in the larger jug. (Hint: use only integers.)
