Answer #1

1. The efficiency for solving the Towers of Hanoi problem recursively is

Group of answer choices

O(n)

O(2n)

O(log n)

O(n2)

Answer:- O(2n)

2. What is the value of this postfix expression: 1 2 * 3 + 4 * + 5 *

Group of answer choices

19

15

70

Answer:- this is not a valid postfix expression


3. Dividing an array into parts is called

Group of answer choices

dividing

separating

sorting

partitioning

Answer:- partitioning

4. The O(n2) analysis of insertion sort is a(n) _______ analysis

Group of answer choices

unknown

best-case

average-case

worst-case

Answer:- average-case worst-case
Explanation:- Insertion sort technique have average-case and worst-case both time
complexity as O(n2). But if you have to choose only one option you must go with average-case.

    (5 marks; questions to Reza) In Lecture 5, Travis said you can prove QuickSort takes N(n log n) time in the best case the same way he proved any comparison-based sorting algorithm takes (n log n) time in the worst case. Give that proof. Notice it doesn't follow directly: e.g., Insertion Sort takes O(n) time in the best case. You can assume QuickSort divides each array into elements less than or equal to the pivot (including the pivot itself) and...
