Solution

The time complexity of searching for an element in a singly linked list is O(n).

Here's why:

  1. A singly linked list is a data structure where each element points to the next element in the list. The last element points to null, indicating the end of the list.

  2. To search for an element, you have to start at the first element and follow the pointers from one element to the next until you find the element you're looking for or reach the end of the list.

  3. In the worst-case scenario, the element you're looking for is at the end of the list or isn't in the list at all. In this case, you would have to look at every element in the list once.

  4. Therefore, the time complexity is proportional to the number of elements in the list, which is O(n), where n is the number of elements in the list.
