- flip_matrix(mat:list)->list You will be given a single parameter a 2D list (A list with lists within it) this will look like a 2D matrix when printed out, see examples below. Your job is to flip the matrix on its horizontal axis. In other words, flip the matrix horizontally so that the bottom is at top and the top is at the bottom. Return the flipped matrix. To print the matrix to the console: print('\n'.join([''.join(['{:4}'.format(item) for item in row]) for row in mat])) Example: Matrix: W R I T X H D R L G L K F M V G I S T C W N M N F Expected: W N M N F G I S T C L K F M V H D R L G W R I T X Matrix: L C S P Expected: S P L C Matrix: A D J A Q H J C I Expected: J C I A Q H A D JC++ You should create a loop which will ask user if they want to insert, delete, display and exit. Then call the corresponding method based on the user's input. The loop will only stop once user entered "Exit" Topic: LinkedListSubject-Object oriented programing Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screen In the same program, use a 'for' loop to print each element of the Array List to the screen.
- 2. ID: A Name: 2. A list of numbers is considered increasing if each value after the first is greater than or equal to the preceding value. The following procedure is intended to return true if numberList is increasing and return false otherwise. Assume that numberList contains at least two elements. Line 1: PROCEDURE isIncreasing (numberList) Line 2: { Line 3: count 2 Line 4: REPEAT UNTIL(count > LENGTH(numberList)) Line 5: Line 6: IF(numberList[count] =. YA198IC11111 2) Name: 2. The following procedure is intended to return the number of times the value val appears in the list myList. The procedure does not work as intended.

Moving the statement in line 5 so that it appears between lines 2 and 3 C. Changing line 6 to IF(item = count) b. Changing line 6 to IF(myList[item] = val) d. Moving the statement in line 11 so that it appears between lines 9 and 10Arithmetic progression def arithmetic_progression(items): An arithmetic progression is a numerical sequence so that the stride between each two consecutive elements is constant throughout the sequence. For example, [4, 8, 12, 16, 20] is an arithmetic progression of length 5, starting from the value 4 with a stride of 4. Given a non-empty list items of positive integers in strictly ascending order, find and return the longest arithmetic progression whose all values exist somewhere in that sequence. Return the answer as a tuple (start, stride, n) of the values that define the progression. To ensure unique results to facilitate automated testing, if there exist several progressions of the same length, this function should return the one with the lowest start. If several progressions of equal length emanate from the lowest start, return the progression with the smallest stride. items expected results [42] (42, 0, 1) [2, 4, 6, 7, 8, 12, 17] (2, 2, 4) [1, 2, 36, 49, 50, 70, 75, 98,…
- struct node{ int a; struct node * nextptr; }; Write two functions. One for inserting new values to a link list that uses the given node structure. void insert(struct node **head, int value); Second function is called to count the number of even numbers in the link list. It returns an integer that represents the number of even numbers. int countEvenNumbers(struct node *head); Write a C program that reads a number of integers from the user and insert those integers into a link list (use insert function). Later pass the head pointer of this link list to a function called countEvenNumbers. This function counts and returns the number of even numbers in the list. The returned value will be printed on the screen. Note 1: Do not modify the function prototypes.

List Member Deletion Modify the list class you created in the previous programming challenges by adding a function to remove an item from the ist and by adding a destructor: void zemove (double x) : Linkedtist (02 Test the class by adding a sequence of instructions that mixes operations for adding items, removing items, and printing the list.Double trouble def double_trouble(items, n): Suppose, if just for the sake of argument, that the following operation is repeated n times for the given list of items: remove the first element, and append that same element twice to the end of items. Which one of the items would be removed and copied in the last operation performed?Sure, this problem could be finger-quotes “solved” by actually performing that operation n times, but the point of this exercise is to come up with an analytical solution to compute the result much faster than actually going through that whole rigmarole. To gently nudge you towards thinking in symbolic and analytical solutions, the automated tester is designed so that anybody trying to brute force their way through this problem by performing all n operations one by one for real will run out of time and memory long before receiving the answer, as will the entire universe.To come up with this analytical solution, tabulate some small cases (you can implement the…
