Q. There is an island that has two kinds of inhabitants, knights, who always tellthe truth, and their opposites, knaves, who always lie. It is assumed that every inhabitant of theisland is either a knight or a knave. Below there are 3 inhabitants, who are denoted by A, B andC.A. What are A, B and C if A says “If B is a knave then C is a knave”, and B says “If Cis a knight then A is a knave”? Briefly explain your reasoning.B. What are A,B and C if A says “B is a knight and C is a knight”, and B says “A is aknight if and only if C is a knave”? Briefly explain your reasoning.
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,…

2. A safe has 5 locks v, w, y and z; all of which must be unlocked for the safe to open. The keys to the locks are distributed among five executives in the following manner.Mr. A has keys for locks v and x. Mr. B has keys for locks v and y. Mr. C has keys for locks w and y. Mr. D has keys for locks x and z. Mr. E has keys for locks v and z.a) Determine the minimal number of executives required to open the safe.b) Find all the combinations of executives that can open the safe; write and expression f(A, B, C, D, E) which specifies when the safe can be opened as a function of what executives are present.c) Who is the essential executive?

Computer science. Correct answer will be upvoted else downvoted. You have an at first void cauldron, and you need to blend an elixir in it. The elixir comprises of two fixings: enchantment pith and water. The elixir you need to blend ought to contain precisely k % sorcery substance and (100−k) % water. In one stage, you can pour possibly one liter of sorcery pith or one liter of water into the cauldron. What is the base number of steps to mix a mixture? You couldn't care less with regards to the complete volume of the elixir, just with regards to the proportion between sorcery substance and water in it. A little update: in the event that you pour e liters of embodiment and w liters of water (e+w>0) into the cauldron, then, at that point, it contains ee+w⋅100 % (without adjusting) sorcery substance and we+w⋅100 % water. Input The primary line contains the single t (1≤t≤100) — the number of experiments. The sole line of each experiment contains a solitary integer k…
You will be given a square chess board with one queen and a number of obstacles placed on it. Determine how many squares the queen can attack. A queen is standing on an chessboard. The chess board's rows are numbered from to , going from bottom to top. Its columns are numbered from to , going from left to right. Each square is referenced by a tuple, , describing the row, , and column, , where the square is located. The queen is standing at position . In a single move, she can attack any square in any of the eight directions (left, right, up, down, and the four diagonals). In the diagram below, the green circles denote all the cells the queen can attack from : There are obstacles on the chessboard, each preventing the queen from attacking any square beyond it on that path. For example, an obstacle at location in the diagram above prevents the queen from attacking cells , , and : Given the queen's position and the locations of all the obstacles, find and print the number of…
b. Suppose you are gifted a collection of 3" pokéballs; all of the the pokéballs have the same size and weight except for one which is slightly heavier, and otherwise look and feel exactly the same as the others. You are tasked with identifying the heavy pokéball and have at your disposal a set of balancing scales which can be used to compare the weights of two collections of pokéballs. The scales can show whether the two collections have the same weight, or can show which collection is heavier if the weights are different. Prove using strong induction that you can identify the heavy pokéball out of 3" pokéballs using n weighing operations.
Conway's Game of Life: This is a zero person game with the following rules: (see Wikipedia for example) Any live cell with fewer than two live neighbours dies, as if by underpopulation. Any live cell with two or three live neighbours lives on to the next generation. Any live cell with more than three live neighbours dies, as if by overpopulation. Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction. Remember the oscillator or blinker of 3 cells. You can also find this blinker on Wikipedia. 1 21 1 2 1 21 3. 4 6 4. 6. 4 8. 9 8 9 #1 #2. #3 5.

Jin Mori is like any other student who loves sleeping. Jin Taejin, his grandfather, imposes a waking schedule that Jin Mori must follow to avoid tardiness at his school. The schedule stated that on weekdays, Mori must be awake at "7:00" and at "10:00" at weekends. Taejin added an exemption for their school vacation. If it is their school vacation, the schedule is "10:00" for weekdays and "off" for weekends. If Jin will not follow the schedule, he is not allowed to practice his favorite martial art, taekwondo. Your job is to create a program that will serve as the alarm clock for Jin Mori. Expected Output: Test Case 1: Vacation: False Day: Monday Alarm Time: 7:00 Awake: Yes Be ready for your practice Mori! Test Case 2: (input) (input) (auto generated) (input) Vacation: False Day: Saturday Alarm Time: 10:00 Awake: No (input) (input) (auto generated) (input) You are not allowed to practice your taekwondo!

7- Let's assume that you are a member of a sports team, and your team is participating in a tournament. Your team needs to play against multiple opponents throughout the tournament. Before each of these matches, as per the rules of the game, the captains of the two sides must do a coin toss. If your team does not have a captain, you need to elect someone as a captain. Prior to each game and each coin toss, you may not repeat the process of electing a captain if you already nominated a person as a captain for the team. Basically, from every team member's perspective, there should be only one captain of the team. According to this scenario, which of the following design pattern you choose when designing Captain class ? I) Template Method II) Singleton III) Strategy IV) None of the mentioned a) O|| b) O III c) O I d) IV
