Delete duplicate-value nodes from a sorted linked list

    Hello I tried to solve this with kotlin cause Im Software android Engineer and I feel more familiar with kotlin

    fun removeDuplicates(llist: SinglyLinkedListNode?): SinglyLinkedListNode? {
 var current = list

 while(current?.next != null){
 if(current.data == current.next?.data){
 current.next = current.next?.next
 }else{
 current = current.next
 }
 }
 return list
}

    My logic is correct but Hacker rank has a kind of bug working with nulleables types the same logic in python works correctly why?

    def removeDuplicates(llist):
 current = llist

while current.next is not None:
if current.data == current.next.data:
current.next = current.next.next
else:
current = current.next

return llist
