Delete node snippet
static SinglyLinkedListNode deleteNode(SinglyLinkedListNode llist, int position)
{
var temp = llist;
if(position==0)
{
return llist.next;
}
var i=0;
while(i < position-1)
{
temp=temp.next;
i++;
}
var current = temp.next.next;
temp.next=current;
return llist;
}

Since there is no any instance of Result class created inside Main method so,
I have removed class result and make deleteNode method not public
using System;
using System.Collections.Generic;
