On my linux machine it works fine, when I submit the problem a got compilation error.

#include <iostream>
#include <vector>
using namespace std;
int data;
int last;
vector <int> base;
int pile[2];
vector <int>::iterator it;

int getMax(){
    it=base.end()-1;
    pile[0]+= *it;
    base.erase(it);
    return *it;
}

int getRest(int value){
    int all = 0;
    while(!base.empty()){
        it=base.end()-1;
        all += *it;
        if(value >= all){
            pile[1]+= *it;
            base.erase(it);
        }
        else{
            break;
        }

    }
    return 0;
}

int main(){
    last = 0;
    pile[0] = 0;
    cin >> data;
    while(cin >> data){
        base.push_back(data);
    }
    sort(base.begin(),base.end());
    while(!base.empty()){
        last = getMax();
        getRest(last);
    }
    if(pile[1] >= pile[0]){
    cout << pile[1] - pile[0];
    }
    else{
    cout << pile[0] - pile[1];
    }
    return 0;
}
