Question
What is the optimal time complexity to count the number of nodes in a linked list?a.Ob.None of the abovec.O(log n)d.O(1)
Solution
The optimal time complexity to count the number of nodes in a linked list is O(n). This is because you have to traverse the entire list to count all the nodes, which takes linear time. Here are the steps:
-
Initialize a counter variable to 0. This will keep track of the number of nodes.
-
Start from the head of the linked list.
-
Traverse the list. For each node, increment the counter by 1.
-
Continue this process until you reach the end of the list.
-
The counter now contains the total number of nodes in the linked list.
So, the correct answer is not in the options given. It should be O(n).
