How to determine the execution time of an element search operation in a linked list?

The time to perform a search for an element in a linked list is the time it takes to find the desired element by traversing the nodes of the list.

Since a linked list does not support direct access by index, searching requires sequentially traversing nodes from the beginning to the desired element. This means that in the worst case, the search time will be linear — O(n), where n is the number of elements in the list.

Example: if you need to find an element with the value x, you will have to go through each node, comparing the value, until a match is found or the end of the list is reached.
