Lecture 21



We covered two distinct topics today.

We first saw two ways to build a heap. We analyzed both methods to find that one was O(N log N) and the other O(N).

The second topic was accessing external memory. I used the data projector to present this topic. The presentation is attached.

Next week we will continue discussing external memory concerns and B-trees.
