Took EIMACS test 24, which was on binary trees and heaps. I didn't actually understand binary trees until halfway through the test, though. I thought that they had to be balanced, but they actually don't. EIMACS did a really bad job explaining this! I'm definitely going to do some additional reading on heaps and binary search trees.
Indeed you are! And I'm going to help with that. Trees are one of the most important topics in CS II, and for reasons I mentioned in class, they are not given adequate exposition in eIMACs.
