algorithm to check if the linked list is in ascending order.

Implement an algorithm to check if the linked list is in ascending order.

template bool linklist::isAscending() const{
    nodeptr ptr = head;
    while (ptr->_next)
    {
        if(ptr->_data > ptr->_next->_data)
            return false;
    }
   
    ptr=ptr->_next;
    return true;
}
