    SinglyLinkedListNode* insertNodeAtPosition(SinglyLinkedListNode* head, int data, int position) { SinglyLinkedListNode *newNode,currentNode=head; newNode = (SinglyLinkedListNode)malloc(sizeof(SinglyLinkedListNode)); newNode->data = data;

    if (head == NULL) {
    return newNode;
}

if (position == 0) {
   newNode->next = head;
   return newNode;
}

currentNode = head;
