- Write a function void printSecond(ListNode *ptr) that prints the value stored in the second node of a list passed to it as parameter. The function should print an error message and terminate the program if the list passed to it has less than two nodes.struct insert_at_back_of_dll { // Function takes a constant Book as a parameter, inserts that book at the // back of a doubly linked list, and returns nothing. void operator()(const Book& book) { / // TO-DO (2) |||| // Write the lines of code to insert "book" at the back of "my_dll". // // // END-TO-DO (2) ||| } std::list& my_dll; };Max Absolute In List Function Lab Description Implement function max_abs_val(lst), which returns the maximum absolutevalue of the elements in list.For example, given a list lst: [-19, -3, 20, -1, 0, -25], the functionshould return 25. The name of the method should be max_abs_val and the method should take one parameter which is the list of values to test. Here is an example call to the function print(max_abs_val([-19, -3, 20, -1, 0, -25])) File Name maxabsinlst.py Score There are three tests each worth 2 points Note: You do not need any other code including the main method or any print statements. ONLY the max_abs_val method is required. Otherwise, the autograder will fail and be unable to grade your code. (I.e., do not include the above example in your code.) The above example should be used be test your code but deleted or comment out upon submission. PYTHON LAB
- Write a function list2DigitOdd() that creates and returns a list that contain all positive 2-digit odd numbers.

- 5. The following function indexCounter aims to find and return all the indices of the element x in a list L. if x is not in the list L, return an empty list. However, the implementation has a flaw, so that many times it will return error message. Can you fix the flaw? def indexCounter(L, x): indexList [] startIndex = 0 while startIndex < len(L): indexList.append (L.index (x, startIndex)) startIndex = L.index (x, startIndex) + 1 return indexListEvery time you write a non-const member function for a linked list, you should always think about if that function is preserving your class invariants.

- card_t * moveCardBack (card t *head); The moveCardBack function will take the card in front of the pile and place it in the back. In coding terms, you are taking the head of the linked list and moving it to the end. The function has one parameter which is the head of the linked list. After moving the card to the back, the function returns the new head of the linked list.Having trouble with creating the InsertAtEnd function in the ItemNode.h file below.
