Consider the possibility of using a linked list to add an element at the beginning of the list. In what cases is this justified?

Using a linked list to add an element at the beginning of the list is justified when high performance of the insertion operation at the beginning is important, rather than random access to elements. In a linked list, adding at the beginning occurs in O(1), unlike an array, where shifting elements may be required.

Example situation:

• Frequently adding elements to the beginning of the collection.
• No need for fast index-based access.

Example in Java:

class Node {
    int value;
    Node next;
    Node(int value) { this.value = value; }
}

class LinkedList {
    Node head;
    void addFirst(int value) {
        Node newNode = new Node(value);
        newNode.next = head;
        head = newNode;
    }
}
