6- You have two numbers ABCD and WXYZ (ex: 2345 and 7965). Write an algorithm using Pseudocode that decides whether ABCD is the inverse of WXYZ. (For example, if ABCD is 2356 and WXYZ is 6532 then the algorithm prints "Inverse" otherwise it will print "Not Invers")

Slot Machine Simulation- I need to get answer in Pseudocode A slot machine is a gambling device that the user inserts money into and then pulls a lever (or presses a button). The slot machine then displays a set of random images. If two or more of the images match, the user wins an amount of money, which the slot machine dispenses back to the user. Design a program that simulates a slot machine. When the program runs, it should do the following: Ask the user to enter the amount of money he or she wants to insert into the slot machine. Instead of displaying images, the program will randomly select a word from the following list: Cherries, Oranges, Plums, Bells, Melons, Bars The program will select and display a word from this list three times. If none of the randomly selected words match, the program will inform the user that he or she has won $0. If two of the words match, the program will inform the user that he or she has won two times the amount entered. If three of the words…

Assignment 5B: Keeping Score. Now that we know about arrays, we can keep track of when events occur during our program. To prove this, let's create a game of Rock-Paper-Scissors. For those not familiar with this game, the basic premise is that each player says "Rock-Paper- Scissors!" and then makes their hand into the shape of one of the three objects. Winners are determined based on the following rules: Rock beats Scissors Scissors beats Paper Paper beats Rock At the start of the program, it will ask the player how many rounds of Rock-Paper- Scissors they want to play. After this, the game will loop for that many number of times. Each loop, it will ask the player what item they want to use – Rock, Paper, or Scissors. The computer will randomly generate its own item, and a winner will be determined. The game will then save the result as an element of an array, and the next round will begin. Once all the rounds have been played, the program will say "Game Over" and display a list of who…
Computer Science Question LabThere is only one list of N ingredients in the menu. Every ingredient has its beauty value that does not depend on its taste, but on the way it looks, which is expressed as a positive integer. To order a dish, the customer asks Ramsay to use all the ingredients from L to R (L is strictly less than R). Ramsay knows that the dish will be tasty and not only beautiful if the sum of its ingredients' beauty values is divisible by K. Ramsay does not want to use all the ingredients, so he always excludes one of them. Which one? - The least beautiful one! (in other words - which has the minimal beauty value). Now he wonders - how many segments (L,R) are there such that the sum of their beauty values will be divisible by K after excluding the least beautiful ingredient. Your assignment is to develop a python code that prints the answer for the problem. Sample test case are given below:Input:3 51 2 30utput:1
