Question

What is the average time complexity of accessing the kth element in a linked list?

A) O(1)
B) O(log n)
C) O(n)
D) O(n²)

Answer 1

The average time complexity of accessing the kth element in a linked list is O(n).

Step-by-step explanation:

The average time complexity of accessing the kth element in a linked list is O(n).

This is because in a linked list, each element is only connected to the next element through a pointer. In order to access the kth element, you have to traverse through k-1 elements to reach it. As the number of elements in the linked list increases, the time it takes to access the kth element increases linearly.

For example, if you have a linked list with 100 elements and you want to access the 50th element, you would need to traverse through 49 elements before reaching the desired element.
