The goal is to find out which spaces on the board get landed on the most.You will not simulate the entire game. You will simulate only the movement of pieces, and will keep track ofwhich squares the pieces land on.Official rules httpss://www.hasbro.com/common/instruct/monins.pdfFamiliarize yourself with the game board. (Taken from Amazons product page.)1include_graphics(board.png)Rules for movementThe Monopoly Board is effectively a circle with 40 spaces on which a player can land. Players move from space tospace around the board in a circle (square).The number of spaces a player moves is determined by the roll of 2 dice. Most often, the player will roll the dice,move the number of spaces shown on the dice, land on a space, and end their turn there. If this were the entiregame, there would be an equal probability of landing on all 40 spaces after many turns – and the distribution ofspace frequency would be uniform.There are, however, several rules which create variation in the frequency of landing on different spaces.Go to JailOne space, Go to Jail Sends players directly to jail (there is a jail space on the board). This space never counts ashaving been landed upon. As soon as the player lands here, he is immediately sent to jail, and the jail space getscounted as landed upon. This is the only space on the game board that moves a players piece. The count of howoften this space is landed on will always be 0.2Rolling DoublesIf a player rolls doubles (two of the same number), the player moves his piece, and then gets to roll the dice againfor another move. However, if a player rolls doubles three times in a row, he is sent directly to jail. (The third spacethat the player would have landed on does not count, but the jail space gets counted as landed on.)Card Decks: Chance and Community ChestA player can land on a Chance or Community Chest space. When a player lands on these spaces, he draws acard from the respective deck and follows its instructions. The instructions will sometimes give money to or takemoney from the player with no change in the players position on the board. Other times, the card will instruct theplayer to move to another space on the board. The list of cards that can be drawn from each deck is provided.There are nine cards in the Chance deck that move the players token. There are two cards in the Community Chestdeck that move the players token. All other cards do not move the players token. For the sake of this simulation,you only need to program actions for the cards that move the tokens. There is no need to do anything for get outof jail or any of the other cards.A card may say Move to the nearest railroad or move to the nearest utility or even go to property . . . . In thesecases, the player always moves forward. So if a player is on Oriental Avenue, the nearest railroad is PennsylvaniaRailroad and NOT Reading Railroad.For the sake of this simulation, the Chance and Community Chest get counted as landed on when the playerlands on the Chance or Community Chest space. The player may also generate another count if the card moves theplayer to another space on the board. In those cases, a tally is counted for the Chance/Community Chest space, thetoken is moved, and then a tally is counted for the space where the player ends his turn.JailJail is the most complicated aspect of this simulation.If a player lands on space 11 (Jail) simply from rolling the dice, he is not in Jail. He is just visiting jail. Hegenerates a tally for landing on jail, and his play continues on as normal.A player can be sent to jail in several ways: he rolls doubles three times in a row; he lands on the go to jail space; he draws a card that Sends hims to jail.As soon as the player is sent to jail, his token moves to jail (space 11), he generates a count for landing on jail, andhis turn ends immediately.On the next turn, the player begins in jail and the player will roll the dice. If he rolls doubles on the dice, he getsout of jail and moves the number of spaces the dice show. However, even though he rolled doubles, he does NOTroll again. He takes his move out of jail and his turn ends. If he does not roll doubles, he stays in jail.A player cannot stay in jail for more than three turns. On the third turn he begins in jail, he rolls the dice andmoves the number of spaces the dice show no matter what. If he rolls doubles, he exits but does not roll again. If hedoes not roll doubles, he still exits and does not roll again.Play then continues as normal.For this simulation, each time a player ends his turn in Jail, a tally will be counted as having been landed upon.There are more rules on jail that include paying a fee to get out early, or using a get out of jail free card. We willnot implement those rules. We will simply simulate a long stay strategy for Jail. This means that the player willnever pay the fee to get out jail early. He will roll the dice and only leave jail if he gets doubles or it is his third turnin jail.3Space Definitions: Utilities are Electric Company and Water Works Railroads are: Reading Railroad, Pennsylvania Railroad, B O Railroad, Shortline RailroadThe AssignmentYour assignment is to implement the rules of Monopoly movement.You must use R6 to create an object class Player which will be used to keep track of a player.Part 1You will first demonstrate that you have coded the rules by showing the output of several test cases using presetdice. Your output for this section should match the published results exactly.The output should be very verbose. It should announce the player roles, where the player moves, what spaces gettallies, if they rolled Doubles, etc. Your text output should match as closely as possible.Part 2The next part is to run 1,000 simulations of a two-player game that lasts 150 turns. This is a total of over 3 hundredthousand tosses of the dice – 1000 games x 150 turns x 2 players + additional rolls if the player gets doubles.Your task is to keep track of where the players land. We ultimately want to build a distribution showing whichspaces are most likely to be landed upon. Advance the tokens around the board according to the rules. Keep inmind the special situations involving the cards, jail, and rolling doubles. After 150 turns, reset the game and startover. Simulate 1000 games.Your final output will be two tables of the spaces on the board and their frequencies. Each table will show the spacename, how many times the space was landed upon, and the relative frequency of landing on that space.The first table is arranged in descending order of frequency of landing. (Jail should be #1, Go to jail should be last.)The second table is arrange in the order of the spaces on the board. (Go will be #1, Boardwalk will be last.)Also print a bar graph showing the frequency of how often each space is landed on.You do not have to simulate or track money at all in this simulation.Starter CodeFor your convenience, I have created the necessary data frames for the game board, and the two decks of cards.I have also created several helper R6 classes for you: PresetDice: You will use this for Part 1: the test cases RandomDice: You will use this for Part 2: the simulation of 1000 games. CardDeck: For creating the Chance and Community Chest decks. This reference class shuffles the deck, andeach time a player draws a card, it shows the next card drawn. When all the cards in the deck have been used,it shuffles the deck again. SpaceTracker: For keeping track of all the spaces you land on.Please take the time to read through these R6 class definitions. Understanding the definitions and what the methodsdo will be necessary for completing the assignment.4TipsAt first blush, the Task may seem overwhelming. Break the task into smaller manageable parts. Start with a simulation that moves pieces around the board and keeps track of where they land. (Ive donethis part for you in my example code.) Then add complexity one part at a time. Each time you add something, thoroughly test it to make sure itbehaves the way you want it to. The PresetDice reference class will be very helpful in your testing. For example, you can intentionally createsome dice rolls to test certain situations. Want to test if Chance is working correctly? Set your dice to causethe player to land on Chance. Want to test if doubles is working correctly? Set the PresetDice to producedoubles. If you had purely random dice, you might have to wait for the computer to produce many manyrandom outcomes before you see three doubles in a row.My recommendation in terms of adding complexity: Add code so landing on Go to jail sends the player to jail. Add code that draws from the Chance and Community Chest decks and moves the player accordingly. Keepin mind that some cards have no effect on player movement, while other cards do. Add code to allow players to roll again after doubles but goes to jail if rolling doubles three times in a row. Add code to implement the rules for Jail. Youll need to keep track of whether the player is actually in jail ornot, how many turns the player has been in jail, and the rules for getting out.Grading1. Do NOT print the verbose version for all of 1000 games.2. We will not run your code. The simulation will take time to run, and we do not have the luxury of runningthe entire simulation for all students.3. We will check the output of the test cases.These are the point values of each test case. Test Case 1: 5 points. Turn 1: Player must be sent to jail. Tally at 11 only. Test Case 2: 15 Points. Turn 1: Player ends at Go. Turn 2: Player ends at Reading Railroad. Turn 3: Player goes to Pennsylvania Railroad, goes again, player ends at Water Works. Turn 4: Player ends on Chance. No movement. Tally at: 1, 6, 8 (3), 16, 23, 29, 37 If your Chance cards are not matching mine, make sure your R is up to date and that you are not loadinga saved work space on start up. Test Case 3: 10 points. Turn 1: Player rolls the dice a total of three times and ends at States Ave. Turn 2: Player lands on Community Chest. Does not move. Tally at: 7, 11, 14, 18 Test Case 4: 10 points. Turn 1: Player ends up in Jail. Turn 2: Player stays in Jail5 Turn 3: Player stays in Jail Turn 4: Player exits Jail and lands on Kentucky ave. Tally at: 7, 11 (3), 13, 22 Test Case 5: 10 points. Turn 1: Player ends in Jail. Player does not roll again, despite having rolled doubles. Turn 2: Player stays in Jail. Turn 3: Player rolls doubles and exits Jail. Player does not roll again, despite having rolled doubles. Tally at: 11 (2), 17 Test Case 6: 10 points. Output must match the example outputThat is 60 points.4. We will check the final output of counts in the results tables.Things we are looking for in the results tables (5 points each): Jail should be the most Frequent space landed on. Jail should have a frequency between 10 and 13%. Spots 2 and 3 should be Illinois Ave and Go (possibly switched) New York Ave. and Tennessee Ave. should be in the top 10. Reading Railroad and BO Railroad should be in the top 10. Mediterranean Ave and Baltic Ave should be in the bottom 5. Park Place should be very infrequent. Bottom 10. Go to jail should be landed on 0 times.5. If your test cases and table output matches what we are looking for, you will get full credit.You can hard code the Functions that handle the decks. In other words, you can write something along the lines of## for chance deck…if(carddrawn == 1)code changes player position to space 1 # advance to goif(carddrawn == 2)code changes player position to space 25 # advance to Illinois avenue# etc….Good luck!I know this is a tough assignment. Like everything else in life, sometimes you have to prioritize other things (eg.health, sleep, sanity, etc.) over the task at hand.If you are unable to implement All parts of the solution, that is also okay. I cannot give you full credit, but pleaseindicate what you were able to implement and what you were not able to implement. You will be graded on whatyou were able to complete.如有需要，请加QQ：99515681 或WX：codehelp
