    The C# doesn't compile. Seeing this error even without my code:

    Solution.cs(32,25): warning CS8625: Cannot convert null literal to non-nullable reference type.

    Here is my c++ solution you watch vide explanation here : https://youtu.be/COnfpdhOlN8

    SinglyLinkedListNode* insertNodeAtHead(SinglyLinkedListNode* llist, int data) {
   SinglyLinkedListNode* new_node = new SinglyLinkedListNode(data);
   new_node -> next = llist;
   return new_node;
}

    def insertNodeAtHead(head, data):
    node = SinglyLinkedListNode(data)
    node.next = head
    
    return node

    Heres a really simple and clear code in python

    def insertNodeAtHead(head, data):
    temp = SinglyLinkedListNode(data)
    if not head:
        return temp
    else:
        temp.next = head
        head = temp
        return head
