      return b;
}
int recursive_max_element(int *arr, int len, int idx)
{
      if(idx == len - 1)
      return arr[idx];
      return max_of_two(arr[idx], recursive_max_element(arr, len, idx + 1));
}
int recursive_min_element(int *arr, int len, int idx)
{
      if(idx == len - 1)
      return arr[idx];
      return min_of_two(arr[idx], recursive_min_element(arr, len, idx + 1));
}
