Kuidas määrata seotud nimekirja keskosas oleva elemendi eemaldamise ajakulud?

The time complexity of removing an element from the middle of a linked list depends on whether you have direct access to that element and its previous node.

• If you have a pointer to the element itself and to the previous node (for example, in a doubly linked list), the removal occurs in O(1), as you only need to reconfigure the links.
• If you only have the value or a pointer to the element without access to the previous one, you first need to traverse the list from the beginning to that element, which takes O(n), where n is the number of elements before the one to be removed.

In general, removing from the middle of a linked list is considered an operation with a time complexity of O(n) if there is no direct access to the previous node.
