public static SinglyLinkedListNode insertNodeAtPosition(SinglyLinkedListNode llist, int data, int position) { SinglyLinkedListNode newNode = new SinglyLinkedListNode(data);

    if (position == 0) {
        newNode.next = llist;
        return newNode;
    } else {
        SinglyLinkedListNode temp = llist;
        for (int i = 1; i < position; i++) {
            temp = temp.next;

Great stuff, i really like your way of explaining. Now could you please have a look on my site and let me know about it.

My solution in Java by two ways: iteration and recursion https://github.com/tuphan22028238/DSA/tree/main/BTLinkedList

Certainly, I'd appreciate it if you could share your recommendations for the top websites where I can find the highest-quality gold available in the market.
