Insert a node at a specific position in a linked list

    My C solution. ` SinglyLinkedListNode* insertNodeAtPosition(SinglyLinkedListNode* llist, int data, int position) { SinglyLinkedListNode *newNode = malloc(sizeof(SinglyLinkedListNode *));

    newNode->data = data;

if (llist == NULL) {
    return newNode;
}
SinglyLinkedListNode *current = llist;
SinglyLinkedListNode *temp = malloc(sizeof(SinglyLinkedListNode *));

//temp->data = data;
for (int i = 0; i < position - 1; i++) {
    current = current->next;
}
temp = current->next;
current->next = newNode;
newNode->next = temp;

return llist;

    } `
