{
LinkedList<int> list = new LinkedList<int>();
list.AddFirst(10);

list.AddLast(30);
list.AddLast(40);
//i. Display total number of nodes into the linked list
Console.WriteLine("Total number of nodes:{0}", list.Count);
//ii. Add value : 25 after 20.
list.AddAfter(list.Find(20), 25);
//iii. Add value 5 before 10
list.AddBefore(list.Find(10), 5);
//iv. Check that the list contains value 30, if contains display a message “30 is into the linked list”
if (list.Contains(30)) {
Console.WriteLine("30 is into the linked list");
}
//v. Display the values of all the nodes from the linked list.
foreach (int value in list) {
Console.Write("{0} ", value);
}
Console.ReadKey();
}
}
