For this Question: Given a list of size 2*N in the form as x<sub>1</sub>->x<sub>2</sub>->x<sub>3</sub>.... x<sub>n</sub>, y<sub>1</sub>->y<sub>2</sub>->y<sub>3</sub>,.... y<sub>n</sub>, Your task is to shuffle the list in the form given as x<sub>1</sub>->y<sub>1</sub>->x<sub>2</sub>->y<sub>2</sub>,.... x<sub>n</sub>,->y<sub>n</sub>.<b>User Task:</b>
Since this will be a functional problem, you don't have to take input. You just have to complete the function <b>shuffle()</b> that takes the head node of the linked lists as a parameter.

Constraints:-
1 &le; N &le; 1000Return the head of the modified list.Sample Input:-
3
1 2 3 4 5 6

Sample Output:-
1 4 2 5 3 6

Explanation:
1-> 4-> 2-> 5-> 3-> 6
, I have written this Solution Code: 
#include <bits/stdc++.h>


using namespace std;

#define MEM(a, b) memset(a, (b), sizeof(a))

#define FOREACH(it, l) for (auto it = l.begin(); it != l.end(); it++)

#define IN(A, B, C) assert( B <= A && A <= C)

#define MP make_pair
#define FOR(i,a) for(int i=0;i<a;i++)

#define FOR1(i,j,a) for(int i=j;i<a;i++)

#define EB emplace_back

#define INF (int)1e9

#define EPS 1e-9

#define PI 3.1415926535897932384626433832795
#define max1 10001
#define MOD 1000000007

#define read(type) readInt<type>()

#define out(x) cout<<x<<'\n'
#define out1(x) cout<<x<<" "
#define END cout<<'\n'
#define int long long
void fast(){
ios::sync_with_stdio(0);
cin.tie(0);
cout.tie(0);
}

signed  main()
{
int n;
cin>>n;
int a[2*n];
FOR(i,2*n){
cin>>a[i];}
FOR(i,n){
cout<<a[i]<<" "<<a[n+i]<<" ";
}

}
, In this Programming Language: C++, Now tell me if this Code is compilable or not?
