How is the access order to elements in a LinkedList determined?

In a linked list of type LinkedList, the order of access to elements is determined by the sequence of links between nodes. Each element (node) contains a reference to the next (and in the case of a doubly linked list — to the previous) element.

To access an element at a specific index, a sequential traversal of the list is usually performed from the beginning (or from the end if the index is closer to the end) to the desired node.

For example, in a singly linked list, to access the element at index i:

1. Start from the head of the list.
2. Move to the next element i times.
3. Return the found element.

This means that index access in LinkedList has a time complexity of O(n), unlike an array, where index access is O(1).
