Another interesting idea would be to use a splay tree.

Splay trees are basically your garden variety binary tree, but
they're self-modifying.

(from memory here) Each time your 'find node' function is successful, it
moves the node to the head of the tree, and reorganizes a few pointers.
This makes frequently used nodes very fast to find, and also tends to
balance out the tree over time.

It's simpler than the hash table, uses only as much space as you need
for the nodes, and is just a little slower in actual use.

However, once the hash table routines are written, it doesn't really
matter. The extra space required by the hash table isn't that bad
either. Just wanted to point out another alternative.
