e) On the 7th floor of a fort lives a queen !! The floor has 17 dorms arranged in a row, Each dorm has doors connecting to the adjoining dorm as well as to the outside corridor. The queen sleeps in a different dorm each night by opening the door to an adjoining dorm (either side depending on her mood) and spending the night and the next day in that room, One day the king arrives at the fort and is searching for the queen. The security guard at the fort tells him of the queen's sleeping patterns and informs him that each morning he may knock on one of the outside doors only. If the queen happens to be behind that door, she will open it and consent to talk to him. The king also has a ticket to another neighboring kingdom in 30 days, so he can make at most 30 attempts. Can the king win the hand of the queen, and if so, what is his strategy ? Explain your solution in detail (you may use diagrams to explain if needed).

- A deck of cards contains 52 cards with four suits: club, diamond, heart and spade ranging in values from 2, ... to 10, Jack, Queen, King and Ace. Ace has the highest value in the same suit. Cards can be compared using their face values. A card with higher face value is bigger than a card with lower face value. If two cards have the same face value, then the suit determines the order. Club is smaller than diamond which is smaller than heart which is smaller than spade. For example: club 2 < diamond 2 < heart 2 < spade 2 if compared.Write an interactive Java program that allows you play cards with a computer. For this project, we are going to focus on one suit of the deck of cards. There are only 13 cards (value: 2, ... to 10, Jack, Queen, King and Ace) in a suit. To play:(a). You first pick a suit at random from the four suits (club, diamond, heart and spade), and display the suit. (b) Then you randomly draw a card from the suit, and let computer draw a card from the same…Indian cricket team Players at an winning celebration dine at a circular table on which there is a single fork between each Player. Players either eat or think, and always start dinner thinking. To eat, a Player first picks up the fork immediately to his left and, once successful, picks up the fork immediately to his right. When a required fork is not on the table, the Player waits, neither eating nor thinking, until the fork is returned to the table. After eating, a Player returns both forks to the table. No cutlery is required to think. Your task is to model the above scenario in Java. (a) Write a class called Fork with two public methods, ForkpickUp and ForkputDown. The methods should take no arguments and return no result. An instance of Fork should act as a lock to prevent concurrent access. In other words, once ForkpickUp has been called, all further calls to ForkpickUp should block until ForkputDown is called; when ForkputDown is called, one caller (if any) who is blocked should…Required: Amitabh had a magical cat. That cat once fell down an empty well. As the walls of the well were not completely vertical, the cat could climb up the well. In one day, the cat can climb 1 unit height and the height of the well is h units. The cat starts at the bottom. Every day, a cat would divide into 2 cats. One of them would climb up 1 unit. The other would wait for help. But while waiting it would fall asleep and roll down 1 unit, unless it is already at the bottom, in which case it just remains there. When a cat would reach the top, it would run home toAmitabh. (Schrodinger doesn't know that some of the cats are in a well and so he can't rescue them). It has been d days since the cat fell into the well. How many cats would come out of the well today? You would notice that the number of cats grows very large with each passing day, so output the answer modulo 10^9+7. d = 0 means that the cat has fallen just now and so there's just one cat at the bottom of the well. So you…

Cards can be compared using the face value. A card with higher face value is bigger than a card with lower face value. If two cards have the same face value, then the suit determines the order. Club is smaller than diamond which is smaller than heart which is smaller than spade. For example: club 2 < diamond 2 < heart 2 < spade 2 if compared. Write an interactive Java program that allows a user to randomly pick a card from the deck of 52 cards (using a random number between 1 and 4 to represent the four suits: club, diamond, heart and spade and then another random number to represent the face value) to play. Show the suit and face value of the user card. Then the program acts as a card dealer which randomly draws another card and displays the card (again showing the suit and face value of…Wooden FenceRecently, Vincent has just bought a farm. He plans to enjoy his retirement by raising horses and goats onhis new farm. In order to do that, he needs to build a fence to enclose his farm; otherwise, the horses andgoats may escape from his farm. Fortunately, he only needs to build a fence on one side of the farm; theremaining sides are naturally fenced.The fence must be exactly 2 unit high and form a perfect rectangle. Why a perfect rectangle? If the fencehas a hole on the upper part, then a horse might jump over it. On the other hand, if the fence has a hole onthe lower part, then a goat might crawl out of it.Vincent has N boards to be used to build the fence. Each board’s dimension is 1 × Li. Each board may beplaced horizontally (1 × Li) or vertically (Li × 1) as long as the resulting fence has a height of 2.Oh, have we told you that Vincent is infamous for his stinginess? Yes, he’s very stingy. He demands to useALL the available boards; he doesn’t care about the length of…Problem Statement: An election is a formal group decision-making process by which a population chooses a candidate by casting votes. Each candidate is assigned name and a specific symbol. A ballot paper is used to cast the vote. Each ballot paper contains symbols of the candidate. A person can vote a candidate by stamping on a specific symbol. The ballot paper should be considered as a spoilt ballot if a person does not stamp or stamp on more than one symbol. Finally ballot paper has to be dropped in a ballot box. Write a C++ program that reads the information from the user to enter the name of the candidate, the total number of received votes, and the spoilt votes in a local election. The total number of participants (candidates) are 5. If the user mistakenly enters any negative value, the program should consider that value as a positive integer. The program should output the name, total received votes, and the percentage of obtained votes by the winning candidate. The program should…

The course is attended by NN students, numbered 11 to NN. The cook must participate in the presence before each class, i.e. call out the names of the students one by one and indicate which students are present. Each student has a first and last name. To save time, Rajesh only wants to call up students' first names. However, if there are multiple students with the same first name, the Rajesh must call out the full names (first and last names) of all those students. For any student who does not share a first name with any other student, the cook can still only call that student's first name. Help the Rajesh decide for each student whether to call that student's full name or just their first name. Note: Please Answer in java language only.

The chef was tasked with reporting on the parade, so he decided to watch all the snakes first. When he sees the snake first, it will be his head, so he marks the "H". Snakes are long, and when they see the snake finally scurry away, they mark its tail with a "T". In the interim, when the snake is moving around it, or in the time between one snake and the next snake, it marks a '.'. Since the snakes come in a procession and one by one, a valid message would be something like "..H..T...HTH....T.", or "...", or "HT", while "T ...H..H.T", "H..T..H", "H..H..T..T" would be invalid messages (see explanation below). Formally, a snake is represented by an 'H' followed by some (possibly null) '.' and then 'T'. A valid message is one that begins with the (probably zero-length) string '.' and then some (possibly zero) snakes, with some '.'s in between, and finally some (possibly zero)…
- Bowling involves 10 frames. Each frame starts with 10 pins. The bowler has two throws to knock all 10 pins down. The total score is the sum of pins knocked down, with some special rules. For the first 9 frames: If all 10 pins are knocked down on a frame's first throw (a "strike"), that frame's score is the previous frame plus 10 plus the next two throws. (No second throw is taken). If all 10 pins are knocked down after a frame's second throw (a "spare"), that frame's score is the previous frame plus 10 plus the next throw. In the 10th frame, if the bowler's first throw is a strike, or the first two throws yields a spare, the bowler gets a third throw. The 10th frame's score is the previous frame's score plus the pins knocked down in the 10th frame's two or three throws. Given integers represents all throws for a game, output on one line each frame's score followed by a space (and end with a newline). Note that the number of throws may be as few as 11 (strikes in first 9 frames,…One hundred tickets, numbered 1, 2, 3, . . . , 100, are sold to 100 different people for a drawing.Four different prizes are awarded, including a grand prize.
