    Question

    A code flow involves processing a stream of data where

    elements are added to the front and removed from the front. Which type of linked list would provide the most straightforward and efficient implementation for these operations?
    A Singly Linked List Correct Answer Incorrect Answer
    B Doubly Linked List Correct Answer Incorrect Answer
    C Circular Linked List Correct Answer Incorrect Answer
    D Array-based Linked List Correct Answer Incorrect Answer
    E Skip List Correct Answer Incorrect Answer

    Solution

    For operations at the front (head) of the list, a singly linked list allows O(1) insertion and deletion by simply updating the head pointer. Doubly linked lists also offer this, but singly linked lists are simpler if backward traversal isn't needed.
