1. Draw by hand what a 2-3-4 tree looks like after each of the following insertions: 10, 20, 30, 40, 50, 60, 70, 80, and 90. Don't use the Tree234 Workshop applet.
2. Draw by hand what a 2-3 tree looks like after inserting the same sequence of values as in Experiment 1.
3. Think about how you would remove a node from a 2-3-4 tree.
