- The function interleave_lists in python takes two parameters, L1 and L2, both lists. Notice that the lists may have different lengths. The function accumulates a new list by appending alternating items from L1 and L2 until one list has been exhausted. The remaining items from the other list are then appended to the end of the new list, and the new list is returned. For example, if L1 = ["hop", "skip", "jump", "rest"] and L2 = ["up", "down"], then the function would return the list: ["hop", "up", "skip", "down", "jump", "rest"]. HINT: Python has a built-in function min() which is helpful here. Initialize accumulator variable newlist to be an empty list Set min_length = min(len(L1), len(L2)), the smaller of the two list lengths Use a for loop to iterate k over range(min_length) to do the first part of this function's work. On each iteration, append to newlist the item from index k in L1, and then append the item from index k in L2 (two appends on each iteration). AFTER the loop…In Python: Write a recursive function named Multiply2 that multiples by 2 and prints each element in a given list. For example: mylist=[1,2,3,4] Multiply2(mylist) prints: 2 4 6 8 Note: the function takes only one parameter, which is the list on which the operation will be performed. It's ok if the list becomes empty after calling the function.The function that will a single items to the list is Oextend (...) Oadd(...) Oappend(...) Olengthen(...)

Implement functionality to sort the records of the student, matriculation number and course according to two self-selected sorting methods.Write a recursive function named Multiply2 that multiples by 2 and prints each element in a given list. For example: mylist=[1,2,3,4] Multiply2(mylist) prints: 2 4 6 8 Note: the function takes only one parameter, which is the list on which the operation will be performed.Write a function that will accept a list of integers and return the sum of the contents of the list(……if the list contains 1,2,3 it will return 6…..)
- The function swap_list_ends in python takes one parameter, L, which is a list. The function then swaps the first and last items in L and returns the object None. Notice that since L is mutable, the changes the function makes to L are visible back in the calling program. SPECIAL CASE: If the list 'L' is empty, then the function does nothing to L and returns None. For example: Test Result L = [1, 3, 9, 2] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) [2, 3, 9, 1] L = ['super', 'awesome', 'excellent'] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) ['excellent', 'awesome', 'super'] L = [True, False] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) [False, True]* allSame returns true if all of the elements in list have the same value. * allSame returns false if any two elements in list have different values. * The array may be empty and it may contain duplicate values. * * Your solution should contain at most one loop. You may not use recursion. * Your solution must not call any other functions. * Here are some examples (using "==" informally): * * * * * * * * true == allSame (new double[] { }) true == allSame(new double[] {11}) true == allSame (new double[] { 11, 11, 11, 11 }) false == allSame(new double[] { 11, 11, 11, 22 }) false == allSame (new double[] { 11, 11, 22, 11 }) true == allSame (new double[] { 22, 22, 22, 22 }) * */ public static boolean allSame (double[] list) { return StdRandom.bernoulli(); //TODO: fix thisQUESTION: NOTE: This assignment is needed to be done in OOP(c++/java), the assignment is a part of course named data structures and algorithm. A singly linked circular list is a linked list where the last node in the list points to the first node in the list. A circular list does not contain NULL pointers. A good example of an application where circular linked list should be used is a items in the shopping cart In online shopping cart, the system must maintain a list of items and must calculate total bill by adding amount of all the items in the cart, Implement the above scenario using Circular Link List. Do Following: First create a class Item having id, name, price and quantity provide appropriate methods and then Create Cart/List class which holds an items object to represent total items in cart and next pointer Implement the method to add items in the array, remove an item and display all items. Now in the main do the following Insert Items in list Display all items. Traverse…

For example, After calling insert method with the given data your list should be as follows: Insert 50 List:- 50 Insert 40 List:- 40 50 Insert 25 List:- 25 40 50 Insert 35 List:- 25 35 40 50 Insert 40 List:- 25 35 40 40 50 Insert 70 List:- 25 35 40 50 70 b).
