3) Answer the following questions below by showing the final tree for each question:

a) Start from an empty tree, construct a 5-way B-tree for the sequence 16, 5, 14, 18, 15, 20, 7, 9, 3, 17, 10.

b) Start from an empty tree, construct a 5-way B-tree for the sequence 20, 18, 17, 16, 15, 14, 10, 9, 7, 5, 3.

c) Based on the trees you generated above, what is your observation in terms of the relationship between the order of the incoming data and the shape of the tree are you getting the exact same trees when having the same set of data in different order? In what way are the trees similar, in what way are they different?
