AGU Computer Engineering Department created a new mathematical game that can be played with two people. In this game, you are given a list of random integers. At each round, the first player takes two numbers from the list and calculates the sum of these numbers. Then, the second player takes two numbers and makes the same calculation. The higher one is going to take the round and increment the score by 1. At the end of the game, who has the better score will win the game.
Here are the rules for the game:
There are always an even number of items on the list
There are two colors for the players: Green and Red
Green starts the game
At each round, green plays and then red plays
The player takes the first and the last numbers
The game can end Tie when the scores are the same.
The game will end when there is no element to take from the list
Your program will simulate the rounds and find out the winner, Green or Red or Tie. The input will be two lines.

THIS MUST BE DONE IN CORAL:
Cracked Egg 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.
The goal of this milestone is to use Coral to program one of the loops you will need for your finalized program in Project Two. This will help you define the logic, flow, and sequence of the game.
For this work, you will write code in Coral for your selected programming game by accessing the activity in the zyBook. Note that links for each are…

Tokens fall to the lowest position in the chosen column that does not already have a token in it. Once one of the players has placed four of their tokens in a straight line (either vertically, horizontally, or diagonally), they win the game If the board is full and no player has won, then the game ends in a draw. TASK Using the following class descriptions, create a UML diagram and a version of Four in a row game The game must allow for a minimum of two and maximum of four players The game must allow each player to enter their name(duplicate names should not be accepted) The game should give the players the ability to choose how many rows (between four and ten), and how many columns (between four and ten) the game board should have. The code uses several classes, including "Player", "Board","Game" and exceptions for handling errors such as invalid moves and full columns.…arrow_forwardThe game is played in the magic maze, as shown below. The squares are flaming lava pools. If you try to cross them you will die. The grid lines are passageways and are safe to travel in. You can start at any location on the grid but must travel in the passageways. You may travel as far as you want in any direction, but once you turn, you must repeat that distance and you may only make left turns. You may not reverse direction inside the tight passageways. You must end up at the same spot you started at. If you successful, then you gain a magic coin, which automatically appears. You can start over again and again in a different or same starting spot and earn new magic coins, but the routes you take must differ somehow for each magic coin. That is, no magic coins for the exact same route as previously done. If the route varies in any way (perhaps it is the same starting location and ending location as a previous route, but longer), it will earn a new magic coin. Mad Madame Mim has…arrow_forward
- You are hired by a game design company and one of their most popular games is The Journey. The game has a ton of quests, and for a player to win, the player must finish all the quests. There are a total of N quests in the game. Here is how the game works: the player can arbitrarily pick one of the N quests to start from. Once the player completes a quest, they unlock some other quests. The player can then choose one of the unlocked quests and complete it, and so on. For instance, let’s say that this game had only 4 quests: A, B, C, and D. Let’s say that after you complete • quest A, you unlock quests [B, D]. • quest B, you unlock quests [C, D]. • quest C, you unlock nothing [ ]. • quest D, you unlock quest [C]. Is this game winnable? Yes, because of the following scenario: The player picks quest A to start with. At the end of the quest A, the unlocked list contains [B, D]. Say that player chooses to do quest B, then the…arrow_forwardNim is a two-player game played with several piles of stones. 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.

- Control Loops: A high school 1000 students and 1000 lockers. The principal plays the following game: She asks dthe first student to open all the lockers. Shen then asks the second student to close all the even-numbered lockers. The third student is asked to check every third locker. If it is open, the student closes it; if it is closed, the student opens it. The remaining students continue this game . In general, the nth student checks every nth locker. If the locker is open, the student closes it; if it is closed, the student opens it. After all the students have taken their turns, some of the lockers are open and some are closed. Write a program thatprompts the user to enter the number of lockers in a school. After the game is over, the program outputs the number of lockers and the locker numbers of the lockers that are open. Test run your program for the following inputs: 1000, 5000, 10,000. Do you see any pattern developing for the locker numbers that are open in the output?…arrow_forwardA video player plays a game in which the character competes in a hurdle race.

- canMove(int x, int y, int destX, int destY, Side s): This method returns true if the player of color s can move the piece at coordinates (x,y) can move to coordinates (destX, destY) on the board in its current state.
