Mis toimub kiiremini LinkedListis võrreldes ArrayListiga, kui teostatakse elementide lisamise või eemaldamise operatsioone?

In LinkedList, the operations of adding and removing elements are faster than in ArrayList when it comes to inserting or deleting in the middle of the list.

The reason is that LinkedList is a linked list, where each element contains references to its neighbors. To add or remove, it is enough to change a few references, which takes O(1) time if you have a reference to the required node.

In ArrayList, elements are stored in an array, and inserting or deleting in the middle requires shifting all subsequent elements, which takes O(n) time.

However, if you need quick access to an element by index, ArrayList is faster (O(1)), while LinkedList requires traversal (O(n)).

Example:

• Adding in the middle of LinkedList: fast, references change.
• Adding in the middle of ArrayList: slow, elements shift.

Therefore, LinkedList is more efficient for frequent insertions/deletions in the middle of the collection.
