1. Suppose we start with an empty B-tree and keys arrive in the following order. – 1, 12, 8, 2, 25, 6, 14, 28, 17, 7, 52, 16, 48, 68, 3, 26, 29, 53, 55, 45 – Build a B-tree of order 5

– Hints • 17: insert/split/promote • 68: insert/split/promote • 3: insert/split/promote • 45:insert/split/promote

2. Suppose we insert the keys {1,2,3, …, n} into an empty B-tree with degree 5, how many nodes does the final B-tree have?

    Suppose you started with an empty binary search tree. We've seen previously that inserting the keys 1, 2, 3, 4, 5, 6, 7 (in that order) would lead to a binary search tree whose shape we called degenerate. Propose a second ordering of the same keys that would also lead to a degenerate-shaped binary search tree. If possible, propose a third ordering of the same keys that would also lead to a degenerate-shaped binary search tree. If there are no...
