You are given two sorted arrays, A and B, and A has a large enough buffer at the end to hold B. Write a method to merge B into A in sorted order without using any other array space. Implementation instruction:1) Define one array of size 18 for A and the other array of size 5 for B.2) Initialize A by inputting 13 integers in the ascending order, and Initialize B by inputting 5 integers in the ascending order.

#include <iostream>

using namespace std;

int main(){

   int arrayA[18] = {1,2,3,4,5,6,7,8,9,10,11,12,13};

   int n = arrayA.length();

   int arrayB[5] = {14,15,16,17,18};

   for (int i = 0; i < arrayB.length(); i++){

       arrayA[n] = array[i];

       n++;

   }

}

Explanation:

The C++ program defines two arrays namely; "arrayA" and "arrayB". The first array has a space size of 18 while the second array has a size of 5. In the program, the second array is merged into the first array
