(Game: scissor, rock, paper) Write a program that plays the popular scissor–rock–paper game.
Rules: A scissor can cut a paper, a rock can knock a scissor, a paper can wrap a rock.
The program should randomly generates a number 0, 1, or 2 representing scissor, rock, and paper.
The program should prompt the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer WINs, LOSEs, or DRAWs.
Problem Description:
In the Whimsical Library, each book is enchanted with a magical code to ensure the
protection of knowledge. The validation process for these magical codes involves a
combination of mathematical spells.
The validation process is described as follows:
Take the sum of the digits at odd positions from left to right.
Take the sum of the squared digits at even positions from left to right.
If the absolute difference between the results from step 1 and step 2 is a prime
number, the book code is considered valid; otherwise, it is invalid.
Example 1:
Consider the magical book code 86420137.
Step 1. Take the sum of the digits at odd positions from left to right.
8+4+0+3=15
Step 2. Take the sum of the squared digits at even positions from left to right.
6^2+2^2+1^2+7^2=36+4+1+49 = 90
Step 3. If the absolute difference between the results from step 1 and step 2 is a prime
number.
115-901 75 (not a prime number)
Book code 86420137 is invalid.
Example 2:
Now, let's examine the…
Problem D: Different Dice Game
Consider the following game for two players:
The first player rolls a pair of dice of fair six-sided dice. If the two dice show different numbers,
the player's score is the larger of the two numbers. Otherwise, the player's score is the sum of the
two numbers.
At this point, the player is asked if they want to remove their lower die and re-roll one die. If
they say no, the player keeps her score and their turn is over. If they say yes, then they roll one
more die and the number showing on this die replaces the lower of the original two rolls. Then
these two dice rolls are scored accordingly. (For example, if the initial roll was a 2 and 5, if the
player doesn't roll again, she gets 5 points. If she does roll again and obtains a 4, her score is still
5. If she rolled again and obtained a 6, her score would be a 6. If she rollwed again and obtained
a 5, her score would be a 10.)
The second player goes after the first, doing the exact same steps as the first…

- (In Java) In the game Clacker, the numbers 1 through 12 are initially displayed. The player throws two dice and may cover the number representing the total or the two numbers on the dice. For example, for a throw of 3 and 5, the player may cover the 3 and the 5 or just the 8. Play continues until all the numbers are covered. The goal is to cover all numbers in the fewest rolls. Create a Clacker application that displays 12 buttons numbered 1 through 12. Each of these buttons can be clicked to ‘cover’ it. A covered button displays nothing. Another button labelled Roll can be clicked to roll the dice. Include labels to display the appropriate die images for each roll. Another label displays the number of rolls taken. A New Game button can be clicked to clear the labels and uncover the buttons for a new game.arrow_forwardProgramming Language: C++ Develop a Tic Tac Toe game that will match a player against the computer. Do’s: Use a typical 3 x 3 board. The horizontal axis should be labeled A, B, C. The vertical axis should be labeled 1, 2, 3. For Example: the attatched picture. Use User-Defined Functions. Use Branching. Use Loops. Use String functions. Randomly determine who will move first, the human or computer. Assign O to the computer and X to the Human player. Ask the user to select their move using the horizontal and vertical position. For example: A1 for the upper left square, or B2 for the center square. After each move, redraw the board with the X’s and O’s in the right positions. After each game, ask the user if they want to play again. If they do, start the game again. Do not’s: Don’t use User Classes or Objects Don’t use imagesarrow_forward6. You are going to play WAR against the computer. This can be super basic. You can have the user "draw" (pick 2-10, J, Q, K, A) a card, or have both cards randomly generated. You should tell who won, user or computer. Example If I play a 7 and the computer plays a Queen, the computer wins. If I place an Ace and the computer plays a 5, I win. If both the computer andI play a 3, we are at "WAR" - do whatever you want with this. Tie? No one wins? Draw a second card?arrow_forward
- Summary When you borrow money to buy a house, a car, or for some other purposes, then you typically repay it by making periodic payments. Suppose that the loan amount is L, r is the interest rate per year, m is the number of payments in a year, and the loan is for t years. Suppose that i = (r / m) and r is in decimal. Then the periodic payment is (first image which R=....): You can also calculate the unpaid loan balance after making certain payments. For example, the unpaid balance after making k payments is (second image which L'=....) : where R is the periodic payment. (Note that if the payments are monthly, then m = 12.) Instructions Write a program that prompts the user to input the values of L, r, m, t, and k. The program then outputs the appropriate values. Your program must contain at least two functions, with appropriate parameters, to calculate the periodic payments and the unpaid balance after certain payments. Make the program menu driven and use a loop so that the…arrow_forwardHow to attempt? Question : The Card Game One day, Fred and his N friends were playing a card game in which each player throws a card with a number written on it. The cards are such that a number X is written on front of the card, and the negative of that number is written on the back side of the card. This game has the following rules: - Each of the N players is asked to throw a card. After all the N cards are thrown, Fred has to flip one or more cards in consecutive order, only once. Your task is to help Fred flip the cards in such a way that the sum of the numbers, on front face of the cards, is the maximum.arrow_forwardCheck Balanced Parentheses: Implement a Java program to check if a given expression has balanced parentheses.arrow_forward
- Craps is a single player dice game, that proceeds as follows:1. the player rolls 2 six-sided dice once if the total is 7 or 11, the player wins if the total is 2, 3 or 12, the player loses otherwise, the game continues, ... see 2 ... 2. the player the continues to roll the dice repeatedly, until ... the total is the same as the original total (from 1), in which case the player wins the total is 7, in which case the player loses Write a function craps using Python that simulates a single game of craps (may be many rolls) and returns 1 if the player wins and 0 otherwise.

Your code has to recognize the need for the second number and ask for it if required. After performing one operation, the calculator prints the output of the operation. After performing one operation, the calculator must not exit. It has to start again for the next operation. The calculator will be closed if the user writes 'e' as any input. Use functions to perform the operations and the appropriate conditions to prevent common errors such as entering characters as one of the numbers etc. b) Run your code and provide the results for at least one example per operation. - -arrow_forwardArranging Pebbles Write a program that can arrange a group of pebbles into its designated position.
