Insert a Node at the Tail of a Linked List

    My Java solution with o(n) time complexity and o(1) space complexity:

    static SinglyLinkedListNode insertNodeAtTail(SinglyLinkedListNode head, int data) {
        if(head == null) return new SinglyLinkedListNode(data);
        
        SinglyLinkedListNode curr = head;
        while(curr.next != null) curr = curr.next;
        curr.next = new SinglyLinkedListNode(data);
        return head;
    }
