Direction: Continue the attached code below. It can only insert a value to a linkedlist. Your goal is to add new functionality to the linkedlist. You may only choose 3 more functions: 1. getValue - this function should be able to display a node by specifying its position (index). 2. clear - resets the linkedlist by assigning null to head. 3. insertNewHead this function can be used to assign a new head to the linkedlist 4. insertAt - this function can be used to insert a node to a specific location. 5. displayAll this function will display all nodes   import java.util.Scanner; class MainLL { public static void main(String[] args) { Scanner sc = new Scanner(System.in); SinglyLL sll= new SinglyLL(); String msg = "Enter an action: [1] Insert, [2]Get an element, [3] clear, [0] Exit"; System.out.println(msg); int choice = sc.nextInt(); while(choice != 0) { switch(choice) { case 1: System.out.println("Enter a value:"); sll.insert(sc.next());  System.out.println("Successfully added a node!\n" + msg); break; default: System.out.println("Invalid input!
