Program plan:
- Include necessary header files.
- Declare the namespace.
- Define the “main()” function.
- Declare and initialize the necessary variables.
- The “while” checks the condition.
- True, call the function “rand()” to check, car behind the door.
- Select the door using the function “rand()”.
- The “if” loop checks the condition, “door_car” is equal to “door_select”.
- True, open the non-car door.
- Increment the value of the variable “OriginalChoice” by “1”.
- Otherwise, open the non-car door which is not selected by the user.

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?…
The Monty Hall game is a statistical problem: there is a TV show (like the Monty Hall show) that allows
contestants to choose between three doors, A, B, and C. Behind one of these doors is a new car (the
winning door), and behind the other two are goats (the losing doors). After the contestant makes a choice,
the game show host shows a goat behind one of the doors NOT chosen. The contestant is then given a
choice to either switch to the other, non-opened door, or stick with their original guess.
The interesting part of this “game" is the statistics involved –a person has a 1/3 chance of originally picking
a winning door. The other door – that which is not revealed to have a goat but also was not originally
chosen – actually has a 2/3 chance of being a winning door. Therefore, it is in the contestant's best interest
to switch doors.
You will create a program that simulates the Monty Hall game, where the computer plays the role of the
host. The program must have no outputs, but

- Four in a row is a game in which players take turns adding tokens to the columns on the game board. 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.

Your objective is to guide a robot through a labyrinth. 1. Your objective is to guide a robot through a labyrinth. The robot begins at the maze's middle, looking north. You have the option of facing the robot north, east, south, or west. You may tell the robot to travel ahead a particular distance, but it will halt if it comes too close to a wall. i. Create a problem statement for this situation. What is the size of the state space? ii. The only location we need to turn while traversing a labyrinth is at the junction of two or more passageways. This remark may be used to reformulate the issue. What is the current size of the state space? iii. We may go in any of the four directions from any point in the labyrinth until we reach a turning point, and that is the only action we need to do. Using these steps, rephrase the issue. Is it necessary to maintain track of the robot's orientation at this point? iv. We already abstracted from the actual world in our original description…arrow_forward
- Children often play the game of rock, paper, and scissors. This game has two players, each of whom chooses one of the three objects: rock, paper, or scissors. If player 1 chooses rock and player 2 chooses paper, player 2 wins the game because paper covers the rock. The game is played according to the following rules: If both players choose the same object, this play is a tie. If one player chooses rock and the other chooses scissors, the player choosing the rock wins this play because the rock breaks the scissors. If one player chooses rock and the other chooses paper, the player choosing the paper wins this play because the paper covers the rock. If one player chooses scissors and the other chooses paper, the player choosing the scissors wins this play because the scissors cut the paper.

Tic tac toe is a very popular game. Only two players can play at a time. Game Rules Traditionally the first player plays with "X". So you can decide who wants to go with "X" and who wants to go with "O". Only one player can play at a time. If any of the players have filled a square then the other player and the same player cannot override that square. There are only two conditions that may match will be a draw or may win. The player that succeeds in placing three respective marks (X or O) in a horizontal, vertical, or diagonal row wins the game. Winning condition Whoever places three respective marks (X or O) horizontally, vertically, or diagonally will be the winner. Submit your code and screenshots of your code in action.

- Email me the answers to the following questions. If you are not familiar with Peg Solitaire, then look it up online. Peg Solitaire is a game consisting of a playing board with 33 holes together with 32 pegs. In the picture above, the hole in the center is empty and the remaining holes contain pegs. The goal is to remove all the pieces except one, which should be in the center. A piece can be removed by jumping an adjacent piece over it into an empty hole. Jumps are permitted horizontally or vertically, but not diagonally. Your assignment consists of one required part, plus one extra credit part: 1. Explain (in words) why Breadth First Search and Iterative Deepening are not good methods for this problem.arrow_forwardA fish-finder is a device used by anglers to find fish in a lake. If the fish-finder finds a fish, it will sound an alarm. It uses depth readings to determine whether to sound an alarm. For our purposes, the fish-finder will decide that a fish is swimming past if:there are four consecutive depth readings which form a strictly increasing sequence (such as 3 4 7 9) (which we will call "Fish Rising"), orthere are four consecutive depth readings which form a strictly decreasing sequence (such as 9 6 5 2) (which we will call "Fish Diving"), orthere are four consecutive depth readings which are identical (which we will call "Constant Depth").All other readings will be considered random noise or debris, which we will call "No Fish."Create a Python program called "fishfinder_firstname_lastname" that takes 1 input of string of 4 numbers separated with comma. Your program must display "Fish Rising", "Fish Diving.", "Fish At Constant Depth" or "No Fish".Example:30,10,20,20 Must display No…arrow_forwardBob is playing a game. He and his team have come up with a plan to throw a ball so that it can hit the target object. The target is at a distance of X meters from Bob. He is at a height of Y meters from the ground and the target is at a height of Z meters from the ground. Bob can throw the ball with a certain speed Task Determine the speed that he should throw the ball. Notes He is aiming at an angle parallel to the ground. Assume acceleration due to gravity is 10m/s² Example Assumptions • X = 2 • Y=5 • Z=2 Approach It can be calculated that he needs to fire at speeds 2.58m/s at an angle parallel to the ground respectively. The answers are taken up to 2 decimal places only. Hence, the answer is 2.58 m/s. Function description Complete the solve function provided in the editor. This function takes the following 3 parameters and returns the minimum speed required: • X Represents an integer denoting the distance of the target from Bob • Y Represents an integer denoting the height of Bob…arrow_forward
