Output:

False

Note:

  • A collection with a fixed size does not allow the addition or removal of elements after the collection is created, but it allows the modification of existing elements.
  • A collection with a fixed size is simply a collection with a wrapper that prevents adding and removing elements. Therefore, if changes are made to the underlying collection, including the addition or removal of elements, the fixed-size collection reflects those changes.
  • Retrieving the value of this property is an O(1) operation.
