The purpose of the programming assignment is to perform empirical comparative
analysis of several modifications of Quicksort for integer arrays.
A.[80 points] Implement the following:
o basic version of Quicksort as discussed in our textbook;
o Quicksort with switching to Insertion sort when the number of elements in the subarray is
less than or equal to 2% of the original number;
o Quicksort with ‘median-of-three’ partitioning;
o Quicksort with randomly selected pivot value.
• functions from standard libraries implementing Quicksort are NOT allowed;
however, you can use any code from any other sources with proper references;
• for obtaining the working time of each algorithm for a particular array, use the
same function as for part (C) of Project #1; call this function before and after a call
to the function implementing a sorting algorithm;
• run your functions for the following types of arrays containing 1000, 10000 and
100000 integers: random numbers, sorted list, almost sorted list, in which every
10th number is out of order (random number);
• the size of integers is supposed to be from 1 to 10000;
• submit: (1) source code with the results; (2) the analysis of your experiments;
• please, do NOT include original and sorted arrays in your output!
• your source code MUST include information on the name of the programmer and
the purpose of the project, as well as some other comments.
B. [20 points] Analysis of the experiments.
Requirements to the analysis:
• the text must be TYPED;
• your analysis must include theoretical information about the efficiency of Quicksort and
how it may be improved using all approaches suggested in this project;
• experimental results must be clearly presented in the form of the table and graphs;
• I expect to see your conclusions on how well the experimental results correspond to
