Wrong anti-spam code

Formulation

Create a function contentOfTheSecondNode that returns the content of the second node of the linked list. The argument of the function is aHead. It is the pointer that contains the address of the head. If the function receives the nullptr, then the function should return -777. However, if the function receives a pointer to the head of a real linked list, then it should check whether the list has another node. If it does not, then the function should return -555. If has at least two nodes, then the function should return the content of the second node. Your code should replace the text // ??? // below.

long contentOfTheSecondNode(ListNode* aHead){ 
   // ??? //
}
