In all questions you may assume that the users enter inputs as they are asked. For example, if the program expects a positive integer, you may assume that users will enter positive integers.

1. (3 pts) Which of the following would be the appropriate function header for the overloaded post-increment operator for a Linked List of integers (assume you will want to increment was value in the list by one). a. LList& LList::operator+ +(LListNode ptr) b. LList LList::operator+ +(int) c. LListNode& LListNode::operator+ +(int) d. LListNode LListNode::operator+ +(int) 2. (3 pts) When defining a class which will contain a function that cannot be defined in the base class, but must be defined in derived classes, we should define the function as a. Overloaded b. Virtual c. Pure-Virtual d. Abstract 3. (3 pts) Which of the following lines of code would evaluate to false in a binary search tree a. ptr->data > ptr->left->data b. ptr->left->data > ptr->left->left->data c. ptr->right->data > ptr->right->left->data d. ptr->left-data > ptr->right->data 4. (3 pts) Convert the math expression "2+3*4* (6-5) " to post fix form. 5. (3 pts) Evaluate the post fix expression "3 2 6 + * 2 /" to a value. 6. (15 pts) Explain, in English not code, how you would determine the median element in a Linked List
