/**
 * Returns a view of the portion of this list between the specified from, inclusive, and to, exclusive.(If from and
 * to are equal, the returned list is empty.) The returned list is backed by this list, so non-structural changes in
 * the returned list are reflected in this list, and vice-versa. The returned list supports all of the optional list
 * operations supported by this list.
 * This method eliminates the need for explicit range operations (of the sort that commonly exist for arrays).
 * Any operation that expects a list can be used as a range operation by passing a subList view instead of a whole list.
 * Similar idioms may be constructed for indexOf and lastIndexOf, and all of the algorithms in the Collections class
 * can be applied to a subList.
 * The semantics of the list returned by this method become undefined if the backing list (i.e., this list) is
 * structurally modified in any way other than via the returned list.(Structural modifications are those that change
 * the size of this list, or otherwise perturb it in such a fashion that iterations in progress may yield incorrect results.)
