Well, was in the library today. Thought I should save everyone a lot of trouble.
Oh yeah, the Fig 21.1 in this picture is this one over here.
Also, I’m not sure if Ma’m really wanted 21.7 K and L, because as you would see 21.7 does not have sub-problems. I think she really meant 21.6.. either that or I got the wrong book. :O
