CSCI 2315 Assignment 6 Solution




In this assignment you are required to make use of the sorting routines in chapter 8

of you text book. You must ask the user to select which sorting routine he/she wants to

use out of those routines implemented in the book (Insertion Sort, Shell Sort, MergeSort,

or QuickSort). Based on the user input, you need to call the corresponding routine.


You are required to write one main program that will read in any number of integers

and store it in an array of ints (not an ArrayList). What you need to do first is to ask

the user what sorting routine he/she would like to use. Then you need to ask the

user how many integers to be entered as input, and then ask the user to input that

these integers.


Your program will store these integers into an array of integers first. Then your

program is supposed to remove the duplicates out of this array by first sorting the

array (using the user-specified sorting routine), and then removing any duplicates.

Your program must not copy these elements into another array to remove the duplicates,

the duplicates should be removed in place which means in the same array. Also, you must

sort the array first before you start duplicate removal.


Once your array (the same array you started with) has only unique numbers, your program

should print out the array followed by a list of all the numbers that were duplicated.

The numbers that were duplicated can be stored into another array.



The following would be a sample scenario of running your program:


Make your choice of a sorting routine first. Then continue as follows:


Enter the number of integers: 10

Enter the 10 integers: 7 9 8 1 9 24 23 24 9 8


The resulting array is: 1 7 8 9 23 24

The numbers 8, 9, 24 were duplicated in the input.



The only file that is to be submitted is a (or and no other file.
