@Override

  LinkedHashMap<Object, Integer> ret = new LinkedHashMap<>();
  if (list.size() >= 1) {
   Object o = list.get(0);
   if (o != null) {
    if (!(o instanceof Iterable)) {
     throw new IllegalArgumentException("Expected an Iterable, but " + o + " is of type " + o.getClass());
    }
    for (Object obj : (Iterable) o) {
     ret.merge(obj, 1, (k, one) -> k + one);
    }
   }
  }
  return ret;
 }
}
