How is the efficiency of searching for an element in a LinkedList data structure evaluated?

Searching for an element in a LinkedList data structure is estimated to take, on average and in the worst case, O(n) time, where n is the number of elements in the list.

This is because LinkedList does not support direct access to elements by index, and to find an element, you need to traverse the list starting from the head until the desired element is found or the end is reached.

Therefore, the search efficiency in a LinkedList is significantly lower than in arrays or lists that support indexing (for example, ArrayList in Java), where index-based search is O(1).
