Homework 1
(Due on January 17, 2008)
Five commonly used sorting algorithms are listed below:
Bubble sort
Insertion sort
Merge sort
Quick sort
Bucket sort
(1) Please give pseudo code for each algorithm.
(2) Please analyze the time complexity (in Big-Oh notation) of the above algorithms, and
answer the following two questions for each algorithm.
a. What is the time complexity of the average case?
b. What is the time complexity of the worst case?
(3) Please find those algorithms that their time complexity of average and worst case are
different.
(4) Please give example datasets to show average and worst case for those algorithms
found in (3).
