Final answer:
The time complexity of searching a value in a linked list using an efficient algorithm is O(n), which means that the time it takes to search for a value increases linearly with the size of the list.
Step-by-step explanation:
The time complexity of searching a value in a singly linked list using an efficient algorithm is O(n).
This means that the time it takes to search for a value in a linked list increases linearly with the size of the list.
For example, if you have a linked list with 10 elements, it may take up to 10 operations to find a specific value.
