Hey guys, I think I need some help here...
I don't think this problem is hard or anything, but i'm having a hell of a time to get AC here.
This is my code anyways:

#include <iostream>
#include <cstdlib>//10013
using namespace std;
unsigned long nums[2][1000001],n,m,carry=0;
int main()
{
cin>>n ...
