sort(a + 1, a + 1 + n);
  reverse(a + 1, a + 1 + n);

  for(int i = 1; i <= n; i++){
    if(sum1 > sum2){
      sum2 += a[i];
    }
    else{
      sum1 += a[i];
    }
  }

  cout << abs(sum1 - sum2);

let me give you an example 13 14 27
if I understand your solution you are sorting it and then add to left or to the right. in this example the diff is 0 what your program returns?
