Cоnsider аn implementаtiоn оf а Priority Queue using a sorted doubly-linked list (ascending order). To maintain the sorted property, the insert method must find the correct position for the new entry. Java public void insert(K key, V value) { Node newNode = new Node(key, value); Node current = list.header().getNext(); // Traverse the list to find the first element with a larger key while (current != list.trailer() && compare(key, current.getKey()) > 0) { current = current.getNext(); } // Insert the new node before the 'current' node list.addBefore(current, newNode); } What is the worst-case time complexity of this insert(k, v) operation?
