int main() { int n,sum1=0,sum2=0; cin>>n; vector ar(n); for(int i=0;i<n;i++) { cin>>ar[i]; } sort(ar.begin(),ar.end()); reverse(ar.begin(),ar.end()); for(int j=0;j<n;j++) {

        if(sum2>=sum1)
        sum1=sum1+ar[j];
        else
        sum2=sum2+ar[j];
         }

  if(sum1>=sum2)
  cout<<sum1-sum2;
  else
  cout<<sum2-sum1;

return 0;
