            Its working in C, try this out. All test case passed SinglyLinkedListNode* insertNodeAtHead(SinglyLinkedListNode* llist, int data) {

            SinglyLinkedListNode* temp = (SinglyLinkedListNode*)malloc(sizeof(SinglyLinkedListNode));
temp->data = data;
temp->next = NULL;

if(llist == NULL){
    llist = temp;
}else{
    temp->next = llist;
    llist = temp;
}
return llist;

            }

              I dont see a need for if condition here.

              SinglyLinkedListNode* temp = (SinglyLinkedListNode*)malloc(sizeof(SinglyLinkedListNode)); temp->data = data; temp->next = llist; return temp;

                for c++, the following code worked, SinglyLinkedListNode *pNew= new SinglyLinkedListNode(data); if(llist == nullptr){ llist = pNew; }else{ pNew->next = llist; llist = pNew; } return llist;
