Roulette Wheel Colors
On a roulette wheel, the pockets are numbered from 0 to 36. The colors of the pockets are as follows:
- Pocket 0 is green.
- For pockets 1 through 10, the odd numbered pockets are red and the even numbered pockets are black.
- For pockets 11 through 18, the odd numbered pockets are black and the even numbered pockets are red.
- For pockets 19 through 28, the odd numbered pockets are red and the even numbered pockets are black.
- For pockets 29 through 36, the odd numbered pockets are black and the even numbered pockets are red.
Write a class named RoulettePocket. The class’s constructor should accept a pocket number. The class should have a method named getPocketColor that returns the pocket’s color, as a string.
Demonstrate the class in a program that asks the user to enter a pocket number, and displays whether the pocket is green, red, or black. The program should display an error message if the user enters a number that is outside the range of 0 through 36.

Rock Paper Scissors Game Instructions
In the game Rock Paper Scissors, two players simultaneously choose one of three options: rock, paper, or scissors. If both chose the same option, then the result is a tie. However, if they choose differently, the winner is determined as follows:
• Rock beats scissors, because a rock can break a pair of scissors.
• Scissors beat paper, because scissors can cut the paper.
• Paper beats rock, because a piece of paper can cover a rock.
Create a game in which the computer randomly chooses rock, paper, or scissors. Assign the number 1, 2, or 3 to represent one of the three choices. Let the user enter a number. Then determine the winner by comparing the user input and the randomly generated choice of the computer.
Additional instructions:
• The Program should validate all user input.
• Game should ask the user to play again and continue if yes and stop if no.
• Once the user stops playing, program should print the total number of wins.
Dice game
Rules of the game:
The players roll three dice, and the program adds the sides that turn up.
After the first roll of the three dice, a player may choose to roll the dice as many times as they wish until the player gets at least one side 2 from a dice.
When a player gets at least one side 2 from the dice, that player's score drops to zero, and the turn switches to the other player.
Both players play the game for an equal number of turns, and the player who gets a score higher than 18 wins.
If both players get a score higher than 18 within an equal number of turns, the player with the higher score wins.
If both of the players got the same scores, print the scores of the players.
These are the minimum required functions for this program. Design and implement these functions. You can create more functions if you choose to.
Here is the provided starter code:

The following algorithm indicates how the game is played. The game continues until the game is either won
by landing on the red space or lost when the piece moves off either end of the board.
Step 1: Place a game piece on a space that is not red and set a counter to 0.
Step 2: If the game piece is on a yellow space, move the game piece 3 positions to the left and go to step 3.
Otherwise, if the game piece is on a black space, move the game piece 1 position to the left and go to step 3.
Otherwise, if the game piece is on a green space, move the game piece 2 positions to the right and go to step
3.
Step 3: Increase the value of the counter by 1.
Step 4: If game piece is on the red space or moved off the end of the…

- Game Description: Pig is a game that has two players (in our case one human and one computer) that alternate turns. Each player’s goal is to get 100 points rolled on a normal six-sided die first. Each turn consists of the rolling the die repeatedly until you get a 1 or decide to stop. As long as you roll a 2-6, you will add this amount to your total for that turn. But if you roll a 1 during your turn, your turn ends and you receive zero points for that entire turn (erasing all of the progress you made since you last agreed to stop). If you decide to stop rolling at any point in your turn, your points for that turn are then added to the overall score. The overall score is then safe from future rolls. The trick is knowing how long to push it before we should stop and save our gains. See end of this document for an example of a game of pig we should write coding as below In order to explore what is the best strategy for the computer player (i.e. at what score do we stop each computer…arrow_forwardMagic 8 Ball Lab Introduction For this lab, you are going to build a simple magic eight-ball, so you no longer have to make any choices. On that note, if you haven’t, you should watch Interstate 60. All joking aside, you will build a 15 sided magic 8-ball, just for simplicity (an actual one has 20 sides for choices). If you are curious about all the choices, you can read up more on them here. Also, if you need a refresher on if statements, go here. Step 1 - Reading the code First take a look at the provided code. You should change the comments to include your name at the top of the file. Furthermore, you will notice all the functions are ‘stubbed’ out for you. This means we have provided the function signature, and a dummy return value that you will replace completely.

It takes as an argument the game board and should return True if the game is over and False otherwise.arrow_forward9. Tree Age (Python) Counting the growth rings of a tree is a good way to tell the age of a tree. Each growth ring counts as one year. Use a Canvas widget to draw how the growth rings of a 5-year-old tree might look. Then, using the create_text method, number each growth ring starting from the center and working outward with the age in years associated with that ring.arrow_forwardFat Percentage Calculator One gram of fat has 9 calories. If you know the number of fat grams in a particular food, you can use the following formula to calculate the number of calories that come from fat in that food: Calories from fat = Fat grams × 9 If you know the food’s total calories, you can use the following formula to calculate the percentage of calories from fat: Percentage of calories from fat = Calories from fat ÷ Total calories Create an application that allows the user to enter: • The total number of calories for a food item • The number of fat grams in that food item The application should calculate and display: • The number of calories from fat • The percentage of calories that come from fat Also, the application’s form should have a CheckBox that the user can check if he or she wants to know whether the food is considered low fat. (If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat.) Use the following test data…arrow_forward
- You have a maze with obstacles and non-zero digits in it: 9+ 7 8 + 4 1 2 3 4 5 You can start from any square, walk in the maze, and finally stop at some square. Each step, you may only walk into one of the four neighbouring squares (up, down, left, right) and you cannot walk into obstacles or walk into a square more than once. When you finish, you can get a number by writing down the digits you encounter in the same order as you meet them. For example, you can get numbers 9784, 4832145, etc. The biggest number you can get is 791452384, shown in the picture above. Your task is to find the biggest mumber you can get. Input There will be at most 25 test cases. Each test begins with two integers R and C (2 < R,C < 15, R+C < 30), the number of rows and columns of the maze. The next R rows represent the maze. Each line contains exactly C characters (without leading or trailing spaces), each of them will be either # or one of the nine non-zero digits.

After painting the white cells of the board, you want to place the maximum number of dominoes on it, according to the following rules: each domino covers two adjacent cells; each cell is covered by at most one domino; if a domino is placed horizontally (it covers two adjacent cells in one of the rows), it should cover only red cells; if a domino is placed vertically (it covers two adjacent cells in one of the columns), it should cover only blue cells. Let the value of the board be the maximum number of dominoes you can place. Calculate the sum of values of the board over all 2w possible ways to paint it. Since it can be huge, print it modulo 998244353. Input The first line contains two integers n and m (1≤n,m≤3⋅105; nm≤3⋅105) — the number of rows and columns, respectively. Then n lines follow, each line contains a string of m characters.

The user enters its choice in the console. • Each of the empty spots have a corresponding number that the players choose on their turn. If the user enters anything other than the number of an empty spot (not yet filled with "X" or "O"), it will not be accepted, and they will be prompted to enter a correct number. 2 4 7 8 • After each turn, two things need to be done: 1) displaying the updated board 2) checking if anyone has won (it should be printed who has won – the user or the computer).
