In this c++ program you are asked to design a 2 x 2 x 2 Rubik's cube that is filled with numbers instead of colors. The cube, naturally, has six sides that are identified as follows:
The front side is side 0
The right side is side 1
The backside side is side 2
The left side is side 3
The Up side is side 4
The bottom side is side 5
The squares on every side are initially filled with the same side index. This means that the four squares on the front side are filled with 0's, the four squares on the right side are filled with 1's, etc.
You are allowed to move the cube in two directions only:
Horizental move (H or h): The first row moves one step in four sides in this order (0 -> 1 -> 2 -> 3 -> 0)
Vertical move (V or v): The left column moves one step in four sides in this order ( 0 -> 5 -> 2 -> 4 -> 0)
The program accepts from the the user the number of moves he/she wants to make, accepts the sequence of desired moves as shown in the sample case below.…
A supermarket is doing a sales promotion for soft drinks. If one day you buy soft drinks and bring the empty bottles the next day, they exchange each set of K empty bottles for a full one. A customer wants to make the most of this offer and therefore bought several bottles on the first day of the promotion. Now he wants to know how many bottles he will have at the end of the second day of the promotion if he use it to the fullest.
Make a program to calculate this.
Input
The first input line contains integer T (1 ≤ T ≤ 10000), which indicates the number of test cases. In each of the following T lines come two integers N and K (1 ≤ K, N ≤ 10000), respectively the number of soft drinks bought and the number of empty bottles to gain a full.
Output
For each test case print the number of bottles that the customer will have on the second day, if he makes the most of the offer.
C++
Create a Blackjack (21) game. Your version of the game will imagine only a SINGLE suit of cards, so 13 unique cards, {2,3,4,5,6,7,8,9,10,J,Q,K,A}. Upon starting, you will be given two cards from the set, non-repeating. Your program MUST then tell you the odds of receiving a beneficial card (that would put your value at 21 or less), and the odds of receiving a detrimental card (that would put your value over 21). Recall that the J, Q, and K cards are worth ‘10’ points, the A card can be worth either ‘1’ or ‘11’ points, and the other cards are worth their numerical values.
FOR YOUR ASSIGNMENT: Provide two screenshots, one in which the game suggests it’s a good idea to get an extra card and the result, and one in which the game suggests it’s a bad idea to get an extra card, and the result of taking that extra card.

- 1. In the game of Monopoly, a pair of dice are rolled to move a player's piece around the board. If a double is rolled (the dice show the same number), the player receives another roll of the dice. If a double is rolled a second time, a third roll of the dice is received. If a double is rolled on the third occasion, the player forfeits their turn (and goes to Jail). Write a program which simulates two players having 50 turns each (a turn however many dice rolls a player has in a row before it's the other player's turn) and determines: a) the total number of spaces moved by each player; and b) how many times a player rolls a double which results in movement of a piece. Use the randi function. For fun, incorporate the rule that a player cannot leave Jail (cannot move) unless they either roll a double or three turns have passed without rolling a double.arrow_forwardWelcome to the era of Aladdin and the great magic lamp. This is 1st of January and Aladdin will be in jail for one year. He was recently caught for helping forty thieves. Now he has nothing to do. But he knows that Jasmine is waiting for him. At some point he got an idea to give Jasmine a magical program that can find intervals of months from a year. This allows her to easily determine how long it will take for Aladdin to get out. Then Aladdin rubs the magic lamp and The Genie appears. Then he asked The Genie to make such a magical program. Unfortunately the Genie doesn't know programming and he wants your help to create that magical program. Genie will give you N as the day of the year and you have to print in which month that day is.

Each cube is white or black. You can get out of a white cube by going in one of the four directions horizontally or vertically (but you can't go beyond the scope of the room). You can get out in a black cube, but you can't get out of it. There is a mouse and a piece of cheese in the room. The mouse is in a cube (0,0) - white, and the cheese in a cube (n-1, n-1) - black. The mouse can move from cube to cube according to the rules described above. Write a program that finds all the paths that can be moved to the cheese with the mouse and if it appears, display it with ‘*’. An example diagram of the task is shown in the figure: Operating instructions: Compose a recursive function path (int i, int j), receiving as parameters the coordinates of the current position of the mouse (initially 0.0, and then run with parameters (i-1, j), (i + 1, j), ( i, j-1) or (i, j + 1)).arrow_forward
- IN C++ This is a simulated chess game. With this project, I want you to move all the pieces on one side of the board. First: If you are unsure how the pieces of a chess board move, do some research. There is plenty of information out there to instruct how a chessboard functions. Your chess piece movement must follow the rules of the game. Second: This is a one-sided board and used to illustrate how each piece moves. Third: The program must keep track of the location of each piece. By this I mean that if a piece is moving, it must respect the position of the other pieces on the board. Fourth: With each move the user should also be given the option to start a new game or end the program.arrow_forwardn this lab, you complete a prewritten Python program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is make of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering.arrow_forwardWrite a program that asks users when their birthday is.

- Scenario: I am trying to create a recursion function that takes a number from the user. That number then goes through to equations where it squares the number and takes the square root of it. Then, that value is supposed to be sent back through the function, through the same equations. Then, I am trying to output the value of each iteration. The amount of iterations is a random number. This code is in C++ and I am using Visual Studio 2023. I have attached the code I, myself, typed and picture of the output. Also, this is a header file that is being called from my source.cpp file (case 5 in switch case). That is why I am entering 5 as the first input when I run the program. Problem: The output only shows one iteration of calculation, then goes straight back into taking an input from the user. What am I doing wrong?arrow_forwardWrite a C program that compute the perimeter of Circle, Rectangle, Triangle and Square. The program asks the user to specify the shape as follows: C for Circle, S for Square, R for Rectangle and T for Triangle and then it reads the required value to compute the perimeter for that specified shape. Note: the perimeter for the shapes:????l? = ? × ?????? × ?S????? = ? × ????????????? = ? × (????? + ??????) ???????? = ????? + ????? + ????3arrow_forwardWRITE A CODE IN C++ LANGUAGE To implement the multiplayer game with multiple players moving and collecting items concurrently, you can use the following steps: Step 1: Generate a random number between 10 - 99 and multiply it by the last digit of your roll number. Step 2: Divide your roll number with the generated number in step 1 and take the mod of the result with 25. Step 3: If the result in step 2 is less than 10, add 15 to it to get the board size. Step 4: Create an n x n board and initialize it with empty squares and randomly place items on some squares. Step 5: Create a thread for each player and pass the player's ID and starting position to the thread. Step 6: Each player thread should handle the player's movement and item collection. Step 7: When a player moves onto a square that contains an item, the player thread should send a message to the main thread indicating that the player has collected an item and the item's value. Step 8: The main thread should update the…arrow_forward
