Sorting

In this assignment, you are required to implement some sorting algorithms, time their execution for different sized inputs, and satisfy yourself about their complexities by doing simple calculations.

Implement MERGESORT, HEAPSORT, QUICKSORT, and INSERTIONSORT. These methods are called from one main routine to sort N integers, where N = 100, 1000, 10000,

50,000 and 100,000. Use either Java random number or the one in the text on page-329 (pseudo random number generator) to generate the input values. For all 5 input cases, output the time required to perform each sort.

To calculate the time required to sort any input, use "currentTimeMillis" method in [url removed, login to view] class. It returns the current time in milli-seconds. Get that at the beginning and end of each sorting routine to determine the time required to perform the sort.

For input size 100, for each sort, output the sorted sequence also. To save paper, output many integers on one horizontal line.

Create the table of execution times for all sorting algorithms and all input sizes. Knowing that these algorithms take c*n*(log n) or c*n*n time, calculate the value of c for your sample executions of size 50,000. Using these c values for each sort routine, predict the time it will take to sort 100,000 elements and comparing it with the actual time taken, calculate the percent error in your predicted value.

Submit:

1) Source code in hard copy.

2) Hard copy of sorted sequences for each sort for input size 100.

3) Table of execution times for each sort and all input sizes.

4) Calculation of c values for input size 50,000; predicted time to sort 100,000 elements based on this c; %error to actually sort 100,000 elements { (predicted - actual)/predicted * 100 }.

5) EXECUTION READY source code on disk.

Your output must be self-explanatory.

## Deliverables

1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.

2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables):

a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment.

b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.

3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
