3. Answer each of the short questions:
a) For 1000 sorted data, what will be the worst-case runtime if you use a Binary Search
Algorithm? First, use the right formula and then compute.
b) For the same problem as above, if you use the Binary Search Tree algorithm, how would the
runtime be different as compared to the Binary Search Algorithm? Again use the correct
formula and find it out.
c) Given the following Binary search Tree: (The root is 50, it is not showing up correctly on the
image below)
12
17
23
SU
54
72
76
(14)
67
You need to write down the pre-order and post-order data arrangements.
d) Illustrate from the tree given in part (c) how would you delete the root, and what will be the
new tree look like. Explain the algorithm for deleting the root.
