Stuart is working on a program to manage arrays. Given an initial array size and elements, the program resizes the array to twice its original size and fills the additional places with the same original elements. Write a program to help Stuart dynamically allocate the memory for the array using malloc(), and then resize using realloc(), and then print the elements of the resized array.Input format :The first line of input consists of an integer N, representing the initial size of the array.The second line consists of N space-separated integers, representing the initial elements of the sequence.

In realloc(ptr, size), what happens if the size is set to zero?
