Chapter 2, Problem 3PP
Suppose you can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. You can redeem seven coupons for one chocolate bar from the machine. You would like to know how many chocolate bars you can eat, including those redeemed via coupon, if you have n dollars.
For example, if you have 20 dollars then you can initially buy 20 chocolate bars. This gives you 20 coupons. You can redeem 14 coupons for two additional chocolate bars. These two additional chocolate bars give you two more coupons, so you now have a total of eight coupons. This gives you enough to redeem for one final chocolate bar. As a result you now have 23 chocolate bars and two leftover coupons.

Suppose we can buy a chocolate bar from the vending machine for $1 each.Inside every chocolate bar is a coupon. We can redeem six coupons for onechocolate bar from the machine. This means that once you have startedbuying chocolate bars from the machine, you always have some coupons.We would like to know how many chocolate bars can be eaten if we startwith N dollars and always redeem coupons if we have enough for an additional chocolate bar.For example, with 6 dollars we could consume 7 chocolate bars afterpurchasing 6 bars giving us 6 coupons and then redeeming the 6 couponsfor one bar. This would leave us with one extra coupon. For 11 dollars, wecould have consumed 13 chocolate bars and still have one coupon left.For 12 dollars, we could have consumed 14 chocolate bars and have twocoupons left.
Suppose a person can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. A person can redeem 3 coupons for one chocolate bar from the machine. This means that once a person has started buying chocolate bars from the machine, he/she always has some coupons. A person would like to know how many chocolate bars can be bought, if a person starts with N dollars and always redeem coupons, if he/she has enough for an additional chocolate bar.
For example:
With 3 dollars a person could buy 4 chocolate bars after purchasing 3 bars giving him/her 3 coupons and then redeeming the 3 coupons for one bar. This would leave him/her with one extra coupon. Thus, will have 4 chocolate bars and still have one coupon leftover.
For 11 dollars, a person can have 16 chocolate bars and still have one coupon leftover.
For 12 dollars, a person can have 17 chocolate bars and have two coupons leftover.
Write a complete Python program that prompts a buyer to input…
In this program, you will check whether two dominoes match.
Because you can flip a tile, two tiles match if the number on the left or right matches the left or right on the other tile.
You should print all matches. First check a direct match, then try flipping tiles. But don’t flip a tile whose left and right numbers are the same. If there is no match, print "No match".
For example, with the tiles 1 3 and 4 3, print
1 3 3 4
Three of my tests are failing since there are duplicates of the print results. How would I go about to remove the duplicate?

- Let's begin with a lesson in roulette. Roulette is a casino game that involves spinning a ball on a wheel that is marked with numbered squares that are red, black, or green. Half of the numbers 1–36 are colored red and half are black and the numbers 0 and 00 are green. Each number occurs only once on the wheel. We can make many different types of bets, but two of the most common are to bet on a single number (1–36) or to bet on a color (either red or black). These will be the two bets we will consider in this project. After all players place their bets on the table, the wheel is spun and the ball tossed onto the wheel. The pocket in which the ball lands on the wheel determines the winning number and color. The ball can land on only one color and number at a time. We begin by placing a bet on a number between 1 and 36. This bet pays 36 to 1 in most casinos, which means we will be paid $36 for each $1 we bet on the winning number. If we lose, we simply lose whatever amount of money we…arrow_forwardLet's begin with a lesson in roulette.

- Suppose you are a computer salesman and your income depend on the total sales and commissions earned for the computers that you sell. Commission rates vary depending on how many units you sold (see chart below). Your income equals to the total sales plus the commission where the commission equals to total sales times the commission rate. That is, commission = total sales * commission rate and income = total sales + commission. Total Sales Commission rate % Less than 200 sold 8% (totalsales < 200) Greater or equal to 200 sold 10% (totalsales >=200 & totalsales <400) Greater than to 400 sold 12% (if (totalsales >= 400) Use Multiway if, else if (use as many you need) and else correctly Review slides 3-CH-2 Slide 4 and 8 Write the code correctly as show in the chapter slides.

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.

You have w white dominoes (2×1 tiles, the two cells are hued in white) and b dark dominoes (2×1 tiles, the two cells are shaded in dark). You can put a white domino on the board in case both board's cells are white and not involved by some other domino. Similarly, you can put a dark domino if the two cells are dark and not involved by some other domino. Would you be able to put all w+b dominoes on the board if you can put dominoes both on a level plane and in an upward direction?

You can use as many piles and as many stones in each pile as you want, but in order to better understand the game, we'll start off with just a few small piles of stones (see figure 1 below). Pile 1 Pile 1 Pile 2 The two players take turns removing stones from the game. On each turn, the player removing stones can only take stones from one pile, but they can remove as many stones from that pile as they want (please note, a player must remove atleast 1 stone from a pile during his/her turn). If they want, they can even remove the entire pile from the game! The winner is the player who removes the final stone (avoid taking the last stone - see figure 2 below). Pile 2 Pile 3 Pile 3 Let's say its Max (player 1) turn to play. Then Max can win by simply removing a stone from Pile 2 or Pile 3 Draw a game tree (upto depth level 2) for the given version of the Nim game.

- There are a dozen eggs in a basket; some are hard boiled and some are raw. The object of this game is for the user to guess the number of hard-boiled eggs prior to playing the game. The computer then simulates cracking all 12 eggs, using a random number 0 or 1 to simulate raw or hard boiled. The number 0 should represent raw eggs and the number 1 should represent hard boiled. The computer must keep track of the number of hard-boiled eggs. At the conclusion of cracking all 12 eggs, the actual number of hard boiled is compared to the user’s guess, and whether the user won or lost is given as output. PreviousNextarrow_forwardUsing Dart. Create a program that will play the “cows and bulls” game with the user. The game works like this: Randomly generate a 4-digit number. Ask the user to guess a 4-digit number. For every digit the user guessed correctly in the correct place, they have a “cow”. For every digit the user guessed correctly in the wrong place is a “bull.” Every time the user makes a guess, tell them how many “cows” and “bulls” they have. Once the user guesses the correct number, the game is over. Keep track of the number of guesses the user makes throughout the game and tell the user at the end.arrow_forwardA school has been selling raffle tickets to raise funds for the school library. Each ticket is sold for $5,and the school has sold many such tickets. Each ticket has a code. When a ticket is presented at thelibrary book sale, it can be redeemed for $1, $5, or $10. The dollar amount being assigned to each ticketis determined by a lottery before the book sale. Heidi is wondering whether the school is actually losing money out of the raffle.(a) Formulate the null and alternative hypotheses that can be used to determine whether the school islosing money out of the raffle. Note that the issue is whether the school is losing money, not whetherthe school is breaking even.
