What is the time complexity of inserting an element at a specific position in a linked list using iteration?

The time complexity of inserting an element at a specific position in a linked list using iteration is O(n), where n is the number of elements in the linked list.

To insert an element at a specific position in a linked list using iteration, we need to traverse the list until we reach the desired position. This involves iterating through each node in the linked list until we find the position where we want to insert the new element.

In the worst-case scenario, we may need to traverse the entire linked list to reach the desired position. Therefore, the time complexity of this operation is directly proportional to the number of elements in the linked list, resulting in a time complexity of O(n).

It is important to note that if we are inserting an element at the beginning or end of the linked list, the time complexity would be O(1) as we can directly update the head or tail pointers. However, when inserting at a specific position, we need to iterate through the list, resulting in a linear time complexity.
