Python

def printLinkedList(head):
    while head:
        print(head.data)
        head=head.next

Java 8 SinglyLinkedListNode current = head; while (current != null) { System.out.println(current.data); current = current.next; }

Why my code is not working? Javascript mode. In google debbuger is printing each element.

function print (head){ if(head.length == null){ return null } else { for(let i = 0; i < head.length; i++){ console.log(head[i]) } } }

Great challenge for beginners! Just like optimizing code for readability, tools like CapCut make video editing simple and clean—perfect for sharing coding tutorials or walkthroughs

Here is my c++ solution, you can watch the explanation here : https://youtu.be/t3gCqS1F24w

void printLinkedList(SinglyLinkedListNode* head) {

    while(head != nullptr){
        cout << head -> data << endl;
        head = head -> next;
    }
}
