COS 226 Exercises on Binary Search Trees

*References: Section 3.2 in Algorithms, 4th edition (Fall 2010 Preliminary Edition)*

**1. **
Draw the sequence of binary search trees that result when you insert the following keys
in that order into an initially empty tree, as in the figure on
p. 307.
(Draw all of the null links.)
` P R I N C E T O G S`

**2. **
Draw a perfectly-balanced binary search tree with the keys
` A B C D E F G`, such that `D` is the root,
then draw the sequence of BSTs that result when you delete the minimum key,
one by one (using the `deleteMin()` algorithm described on
pages 314-317).
