A for loop would be easier @yatta

I'll try with it

@yatta use this:

ListNode current = nodeList;
for(; current != null; current = current.next){
    Console.WriteLine(current.val);
}

ListNode current = nodeList;
for(; current != null; current = current.next){
    Console.WriteLine(current.val);
}
