Implement Insertion Sort algorithm in Java.

*Insertion Sort:
           Insertion sort is a simple sorting algorithm that works the way we sort playing cards in our hands.

*Advantages of Insertion Sort: 
1) It is very simple.
2) It is very efficient for small data sets.
3) It is stable; i.e., it does not change the relative order of elements with equal keys.
4) In-place; i.e., only requires a constant amount O(1) of additional memory space.

          Insertion sort iterates through the list by consuming one input element at each repetition, and growing a sorted output list. On a repetition, insertion sort removes one element from the input data, finds the location it belongs within the sorted list, and inserts it there. It repeats until no input elements remain.

//A small example to show how to use execvp() function in C. We will have two .C files , EXEC.c and execDemo.c and we will replace the execDemo.c with EXEC.c by calling execvp() function in execDemo.c . //EXEC.c  #include<stdio.h>  #include<unistd.h>  int main()   {        int i;       printf("This  is EXEC.c, called by execvp() ");        printf("\n");       return 0;   }  Now,create an executable file of EXEC.c using command  gcc EXEC.c -o EXEC //execDemo.c #include<stdio.h> #include<stdlib.h>  #include<unistd.h>  int main()  {     //A null terminated array of character      //pointers       char *args[]={"./EXEC",NULL};       execvp(args[0],args);     /*All statements are ignored after execvp() call as this whole process(execDemo.c) is replaced by ...

Implement a class CppArray which is identical to a one-dimensional C++ array (i.e., the index set is a set of consecutive integers starting at 0) except for the following : 1. It performs range checking. 2.It allows one to be assigned to another array through the use of assignment operator. 3.It supports a function that returns the size of the array.
