Whew, that was a lot of information about structures. Before we continue our walk in the next chapter with a completely different topic, I’ll leave you with this summary thought. Let \(BST\) be the set of Binary Search Trees, and \(BT\) be the set of Binary Trees. Let \(RT\) be the set of rooted trees, and \(T\) be the set of trees (free or rooted). Finally, let \(CG\) be the set of connected graphs, and \(G\) the set of all graphs. Then we have:
\[BST \subset BT \subset RT \subset T \subset CG \subset G.\]
It’s a beautiful thing.
