What is the space complexity for deleting a linked list?Select one:a.O(1).b.O(n).c.Either o(1) or o(n).d.O(logn).

To determine the space complexity for deleting a linked list, let's analyze the process step by step:

1. Understanding the Task: Deleting a linked list means removing all the nodes from the list and freeing the memory they occupy.

2. Iterative Deletion: Typically, we delete a linked list by iterating through each node, deleting it, and moving to the next node until we reach the end of the list.

3. Space Complexity Analysis:

   • Auxiliary Space: This refers to the extra space or temporary space used by an algorithm, excluding the input data.
   • In the case of deleting a linked list, we usually use a single pointer (or reference) to traverse the list. This pointer is used to keep track of the current node being deleted.
   • Since we are only using a constant amount of extra space (the pointer), the space complexity is O(1).

4. Conclusion: The space complexity for deleting a linked list is O(1) because we only need a constant amount of extra space to perform the deletion.

Therefore, the correct answer is: a. O(1)
