Write a Program to find the maximum and minimum value node from a singly linked list

Solution:

using System;

namespace LinkedListOpearation
{
    class Program
    {
        public static void Main()
        {
            var linkedList = new LinkedList();
            linkedList.Add(6);
            linkedList.Add(1);
            linkedList.Add(5);
            linkedList.Add(2);
            linkedList.Add(3);
            linkedList.Add(9);
            Console.WriteLine("Sorted Linked List is:");
            linkedList.Print(linkedList.Head);
            Console.WriteLine($"Min node: {linkedList.MinNode()}");
            Console.WriteLine($"Max node: {linkedList.MaxNode()}");
            Console.ReadLine();
        }   
    }

    
    public class LinkedList
    {
        public Node Head;
        
        public void Add(int data)
        {
            var node = new Node(data) {Next = Head};
            Head = node;
        }

        public int MinNode()
        {
            var current = Head;

            if (Head == null)
                throw new Exception();

            var min = Head.Data;

            while (current != null)
            {
                if (min > current.Data)
                    min = current.Data;

                current = current.Next;
            }

            return min;
        }

        public int MaxNode()
        {

            var max = Head.Data;

            while (current != null)
            {
                if (max < current.Data)
                    max = current.Data;

                current = current.Next;
            }
            return  max;
        }

        public void Print(Node head)
        {
            while (head != null)
            {
                Console.WriteLine(head.Data);
                head = head.Next;
            }
        }
    }

    public class Node
    {
        public int Data;
        public Node Next;

        public Node(int data)
        {
            Data = data;
        }
    }
