What is the worst-case time complexity for searching an element in an unsorted linked list?

Step 1: Understand what a linked list is. A linked list is a collection of nodes where each node contains data and a reference to the next node.
Step 2: Know that an unsorted linked list means the elements are not in any particular order.
Step 3: When searching for an element, you start at the head (the first node) of the linked list.
Step 4: You check each node one by one to see if it contains the element you are looking for.
Step 5: In the worst-case scenario, the element you are searching for is either not in the list or is at the very end of the list.
Step 6: If the linked list has 'n' nodes, you will have to check all 'n' nodes to find the element or confirm it is not there.
Step 7: Therefore, the time it takes to search in the worst case is proportional to the number of nodes, which is O(n).
