Question

A class Combine contains an array of integers which combines two arrays into a single array including the duplicate elements if any and sorts the combined array .Some of the members of the class are given below:
Classname:Combine
Data members / instance variables:
com[ ]:integer array
size: size of the array
Member functions/methods:
Combine(int nn): parameterized constructor to assign size= nn

void inputarray():to accept the array elements
void sort():sorts the elements of combined array in ascending order using the selection sort technique
void mix(Combine A,Combine B):combines the parameterized object arrays and stores the result in the current object array along with duplicate elements if any
void display():displays the array elements

Specify the class Combine giving details of the constructor( int),void inputarray(),void sort() , void mix(Combine,Combine) and void display(). Also define the main() function to create an object and call the methods accordingly to enable the task.
