Max Jones belongs to a CD (compact disc) club that allows him to buy CDs at a much lower price than his local music store charges. He wants to know how much he saves by buying all of his CDs through the club rather than through the music store. The output is the savings. The input is the number of CDs purchased, the club CD price, and thestore CD price. The algorithm should use two processing items: one for the cost of buying the CDs through the club, and the other for the cost of buying the CDs through the store. Write the algorithm using pseudocode.
Your team was asked to program a self-driving car that reaches its destination with minimum travel time.
Write an algorithm for this car to choose from two possible road trips. You will calculate the travel time of each trip based on the car current speed and the distance to the target destination. Assume that both distances and car speed are given.

- Your team was asked to program a self-driving car that reaches its destination with minimum travel time. Write an algorithm for this car to choose from two possible road trips. You will calculate the travel time of each trip based on the car current speed and the distance to the target destination. Assume that both distances and car speed are given.

There are two ways to change the coins: • flip over any ten coins, or • place n+ 1 additional coins, all showing tails, on the table where n is the number of heads currently showing on the table. For example, you might begin by flipping nine heads and one tail, yielding 90 heads and 12 tails, then add 91 tails, yielding 90 heads and 103 tails. (a) Model this situation as a state machine, carefully defining the set of states, the start state, and the possible state transitions. (b) Optionally, explain how to reach a state with exactly one tail showing. (c) Consider the following derived variables: C ::= the number of coins on the table H ::= the number of heads on the table T::= the number of tails on the table C, ::= parity (C) H2 ::= parity(H) T2 ::= parity(T) Here the parity : Z → {0,1} function is defined as parity(n) = 0 when n is even and 1 otherwise. Which of these variables is strictly…arrow_forwardJerry Feingold wants a program that will help him calculate the amount to tip a waiter at a restaurant. The program should subtract any liquor charge from the total bill and then calculate the tip (using a percentage) on the remainder. Finally, the program should display the tip on the screen. Desk-check your solution’s algorithm using $85 as the total bill, $20 as the liquor charge, and 20% as the tip percentage. Then desk-check it using $35 as the total bill, $0 as the liquor charge, and 15% as the tip percentage.arrow_forward
- A consumer can withdraw up to $500 per day from an ATM. If a customer withdraws more than $300, the service charge is 4%. It tells the consumer of inadequate cash and offers to withdraw the money for a fee of $25.00. The ATM won't let you withdraw money if your account is empty or has a negative balance. If the withdrawal exceeds $500, the ATM informs the customer of the maximum withdrawal amount and refuses the withdrawal. Write an algorithm that allows customers to enter withdrawal amounts. The algorithm then verifies the account balance, debits the customer's account for the amount withdrawn plus any service fees.arrow_forwarda program that implements the algorithm that you designed in Exercise 34 of this chapter (Chapter 4). The instructions to Exercise 34 have been posted below for your convenience. Exercise 34 Suppose that billingAmount is a double variable, which denotes the amount you need to pay to the department store. If you pay the full amount, you get $10.00 or 1% of the billingAmount, whichever is smaller, as a credit on your next bill; If you pay at least 50% of the billingAmount, the penalty is 5% of the balance; If you pay at least 20% of the billingAmount and less than 50% of the billingAmount, the penalty is 10% of the balance; otherwise the penalty is 20% of the balance. Design an algorithm that prompts the user to enter the billing amount and the desired payment. The algorithm then calculates and outputs the credit or the remaining balance. If the amount is not paid in full, the algorithm should also output the penalty amount. Examples of the program are shown below: Enter the billing…arrow_forwardThe greatest common divisor of two positive integers, A and B, is the largest number that can be evenly divided into both of them. Euclid's algorithm can be used to find the greatest common divisor (GCD) of two positive integers. You can use this algorithm in the following manner: 1. Compute the remainder of dividing the larger number by the smaller number. 2. Replace the larger number with the smaller number and the smaller number with the remainder. 3. Repeat this process until the smaller number is zero. The larger number at this point is the GCD of A and B. Write a program that lets the user enter two integers and then prints each step in the process of using the Euclidean algorithm to find their GCD. An example of the program input and output is shown below: Enter the smaller number: 5 Enter the larger number: 15 The greatest common divisor is 5arrow_forward
- Create the algorithm for the following problem: A company is giving out bonus to the employees relative to the number of years worked. For example, if the person is employed for 1 year or less, bonus is 1%, 2 years is 2%, 3 years is 3% and so on. Your program will calculate the bonus by asking user for annual salary and number of years worked. Calculate and display the bonus amount. Hint: bonus rate = numofyears/100arrow_forwarddefinitely pick 2 coins and win. If there are 3 coins and Alice is still the first player to pick, the game. For example, if there are 2 coins and Alice is the fitst player to pick, she will no matter she picks I or 2 coins, Bob will get the last coin and win the game. Given number of coins and the order of plavers (which means the first and the second players pick the coins), you are required to write a program to calculate the winner of the ga and calculate how many different strategies there are for heishe to win the game. should use recursion to solve the problem, and the parameters are read from the commnana line. You can assume that there are no more than 30 coinarrow_forwardWrite a program that will figure out the required change for a purchase. Start by asking the user for the price of the product and the amount paid. (We are expecting that the user will give a larger value for the amount paid.) Read in each of these values as a double. Report back to the user the number of each denomination of change due. You are not just telling the user the amount of money he gets back. Hint: Working with integers is much easier. The modulo operator is your friend for this assignment. Also, note that pennies can be tricky due to the poor real number to binary conversions. (Remember that 1.00 could actually be stored as 0.9999999999997.) Do not include five-dollar bills, ten-dollar bills, etc. Only show coins and one-dollar bill amounts. Be sure to test multiple values. There is a test case below. Your program should run the test case exactly as it appears below, and should work on any other case in general.

- Write a program that plays a number guessing game with a Human user. The Human user will think of a number between 1 and 100, inclusive. The program will make guesses and the user will tell the program to guess higher or lower. A sample run of the program might look like this: Ready to play (y/n)? y Think of a number between 1 and 100. My guess is 50. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: h My guess is 75. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: h My guess is 88. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: l My guess is 81. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: c Great! Do you want to play again (y/n)? y Think of a number between 1 and 100. My guess is 50. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: l My guess is 25.

The rules are: roll two dice if the sum equals 7, win $4 if the sum is not 7, lose $1 Write a program that asks the user how much they would like start the game with. The program should then: simulate the dice roll (using the random function) and show what was rolled show what the user’s funds are after each roll ask the user if they want to roll again if the user wants to roll again, repeat the three actions above if the user does not want to roll again give some response and end the game the final output should show if they won or lost money, and how many rolls they playedarrow_forwardWrite a program that checks to see if the user won the lottery. Assume the winning lottery numbers are 8, 13, 27, 53, and 54. Ask the user for five numbers and compare those numbers to the winning numbers to determine how many matches the user got. In a lottery, the order of the numbers doesn't matter.arrow_forward
