- 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.

- In C++ Plz LAB: Grocery shopping list (linked list: inserting at the end of a list) Given main(), define an InsertAtEnd() member function in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list.

Ex1) If n = [1, 2, 3, 4, 5, 6], remove_evens(n) returns [1, 3, 5].

Practice with use of Java exceptions. Practice use of generics. You have been provided with java code for SomeList<T> class. This code is for a general linked list implementation where the elements are not ordered. For this assignment you will modify the code provided to create a SortedList<T> class that will maintain elements in a linked list in ascending order and allow the removal of objects from both the front and back. You will be required to add methods for inserting an object in order (InsertInorder) and removing an object from the front or back. You will write a test program, ListTest, that inserts 25 random integers, between 0 and 100, into the linked list resulting in an in-order list. Your code to remove an object must include the exception NoSuchElementException. Demonstrate your code by displaying the ordered linked list and…value_list is read from input. shift_right() has one parameter list_to_modify, and shifts list_to_modify right. Call shift_right() with a copy of the list value_list as the argument to avoid modifying value_list. Ex: If the input is: The best is yet to come, and won't that be fine then the output is: Shifted right: ['fine', 'The', 'best', 'is', 'yet', 'to', 'come,', 'and', "won't", 'that', 'be'] Original: ['The', 'best', 'is', 'yet', 'to', 'come,', 'and', "won't", 'that', 'be', 'fine']
