- How 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_forwardCredit Card Number Check. The last digit of a credit card number is the check digit, which protects against transcription errors such as an error in a single digit or switching two digits. The following method is used to verify actual credit card numbers but, for simplicity, we will describe it for numbers with 8 digits instead of 16:• Starting from the rightmost digit, form the sum of every other digit. For example, if thecredit card number is 4358 9795, then you form the sum 5 + 7 + 8 + 3 = 23.• Double each of the digits that were not included in the preceding step. Add all digits ofthe resulting numbers. For example, with the number given above, doubling the digits,starting with the next-to-last one, yields 18 18 10 8. Adding all digits in these valuesyields 1 + 8 + 1 + 8 + 1 + 0 + 8 = 27.• Add the sums of the two preceding steps. If the last digit of the result is 0, the number isvalid. In our case, 23 + 27 = 50, so the number is valid.Write a program that implements this…arrow_forwardQ7: (Find the second lowest integer number) Write a program that prompts the user to enter a set of integer numbers, and finally displays the second lowest integer number in the set.

A number is called deficient if the sum of its divisors is less than the original number. A number is called abundant if the sum of its divisors is more than the original number. Write a program that answers the following questions: What numbers below 5000 are perfect? What odd numbers below 5000 are abundant? What are the relative proportions of deficient, abundant, and perfect numbers? 5000 should be in a global constant.arrow_forward(Check password) Some websites impose certain rules for passwords. Write a method that checks whether a string is a valid password. Suppose the password rules are as follows: A password must have at least eight characters. A password consists of only letters and digits. A password must contain at least two digits. Write a program that prompts the user to enter a password and displays Valid Password if the rules are followed or Invalid Password otherwise.arrow_forward
- (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.arrow_forwardDirections: Write a program that will perform a casino game using C. Provide comments in the codeexplaining everything. See above deliverable instructions. Requirements: A menu will first appear asking the user to choose which game they would like to play. The userwill be able to choose between blackjack and roulette.The blackjack game will only play one hand at a time against the dealer. If the dealer and the user have the same,then it’s a draw. If you do not know how to play blackjack, then you might need to research the game.The roulette game will ask the user what numbers they would like to bet on. If the random number is chosen, thenthe user wins.Each game should ask the user how much money they would like to bet before the game starts. The user shouldhave a starting amount of money, once the user loses their money, the user will then need to stop playing. Expert Solutionarrow_forwardSee the sample outputs for more clarification.

You can do this several ways. one way is to add the length and width of each rectangle to get it's area and then compare the two areas together. • The program should ask for the length and width of two rectangles and then tell the user which rectangle has the greater area, or if the areas are the same. • The area of a rectangle is the rectangle's length times its width. Name the source code file yourName HW4.py. • Test and run the program. Capture the output console and save it as an image file named yourName HW4 output.jpg. • Submit the py and the image files through Canvas.

We have 4 types of pebbles: Red, white, blue, and green colored pebbles. Supposed that we have an n-number of pebbles, the program should be able to check the color of the pebble and arrange them in such a way that it will look something like this: Example, if there are 9 pebbles; 1 green, 3 white, 2 blue, and 3 red, the program will output something like this: RRRWWWBBG NOTE: The program will let the user to enter the pebbles and then the program will automatically arrange it.
