A boatman, a wolf, a sheep, and a cabbage are on the bank of a river. They have a small boat that is capable of carrying the boatman and at most one other animal/item with him. However, if left alone by the boatman, the wolf can eat the sheep, and the sheep can eat the cabbage. How can all four be moved safely to the opposite bank of the river? Here is a nice visualization of the whole process in the original game. Disclaimer: writers, testers and CodeChef are not related to this link. This leads to a more general problem. If there are other groups of animals/items with the boatman, is it possible to move them all to the opposite bank of the river in such a way that nobody/nothing gets eaten? We will give you the number of animals/items (not including the boatman). Moreover, we will give you all a list of pairs of the form "X Y" where the X-th animal/item will be eaten by the Y-th one if they are both on the opposite bank to the boatman. You are to determine whether it is possible to achieve the task or not. Input: 32 12 23 Output: YES Solve using Python

Please read the thickened sentences below In this game, one flyand three frogs are placed randomly on a board with the size 7x7.In each iteration, they move randomlywithin the board, and the simulation stops when one of the frogs eats the fly.Fly and frogs are essentially creatures that can move, make noise, and eat. Frogs can move up to 2squares in any direction, and flies can move up to 1. Frogs make the "Croak! Croak!" sound, and fliesmake "ZzzZZz!". Since frogs should not eat their kind, a function of "isEatable" should also beimplemented in decision making. A variable or function to check if the fly is alive is also required as aterminate condition for simulation.In each iteration, an 'f' character represents frogs' position on board, and an '*' character is used torepresent the position of fly.

Implement an algorithmic solution, indicating which states are valid and which are not, and model the space of the following problem: An interest group from a small town decided to sue a company for commercial abuse. For this, the people have organized themselves and decided to send 3 representatives, who will have to travel in a Van to the city where the lawsuit will be filed. The company to be sued, upon learning of these actions, has decided to send 3 lawyers to persuade the representatives, who will also travel in the same Van for that purpose. The community must file the class action suit under these conditions: - The three applicants must reach the destination city; - Only two people can travel per trip in the Van (small town - city, city - small town); - There can never be more lawyers than plaintiffs in any one place (either in the small town or city) because the lawyers can persuade the plaintiffs and as a consequence, the lawsuit would not be made; - The Van cannot be…
You and your friends decided to hold a “Secret Santa” gift exchange, where each person buys a gift for someone else. To see how this whole thing works, let’s consider the following example. Suppose there are 7 people A, B, C, D, E, F, and G. We denote x → y to mean “x gives a gift to y.” If the gift exchange starts with person A, then they give a gift to E. Then E gives a gift to B. And it is entirely possible that B gives a gift to A; in such a case we have completed a “cycle.” In case a cycle occurs, the gift exchange resumes with another person that hasn’t given their gift yet. If the gift exchange resumes with person D, then they give a gift to G. Then G gives a gift to F. Then F gives a gift to C. Then finally C gives a gift to D, which completes another cycle. Since all of the people have given their gifts, the giftexchange is done, otherwise the gift exchange resumes again with another person. All in all, there are two cycles that occurred during the gift exchange: A → E → B → A…
A tile of a monkey puzzle has four monkey halves that can be labelled as north(N), east (E), south (S), and west (W) half. In addition to the shape of the borderrectangle, these halves determine which edges can be placed next one other. There isalso another way to define how the tiles can be placed: Each tile corner (i.e. compassdirections NE, SE, SW, and NW) has a monkey quarter. If we abstract this quarter, forexample, with a letter, only the tiles with the same letter in their touching corners canbe adjacent. illustrates one valid solution for this quarter monkey puzzle.Are the two monkey puzzle representations equivalent in the sense that if we have apile of ‘half monkey’ tiles H, it is possible to define a pile of ‘quarter monkey’ tilesQ that gives exactly the same set of solutions for the puzzle (and vice versa)?
Please help me Josephus Problem is a theoretical problem related to a certain counting-out game. On thiscase, people are standing in a circle waiting to be executed. After a specified number ofpeople are skipped, the next person is executed. The procedure is repeated with theremaining people, starting with the next person, going in the same direction and skippingthe same number of people, until one person remains, and is freed.Arrange the numbers 1 , 2, 3 , ... consecutively (say, clockwise) in a circle. Now removenumber 2 and proceed clockwise by removing every other number, among those thatremain, until one number is left. (a) Let denote the final number which remains. Find formula for .(b) If there are 70 people, what is the safe number (the number that remains)?

Suppose you have a large collection of photos from your trips, including photos of yourself alone, photos of yourself with other people, photos of other people without you, as well as photos without people. These images look more sharp or more detailed if we are able to perceive all the objects and their shapes correctly in it. For example. An image with a face, looks clear when we are able to identify eyes, ears, nose, lips, forehead e.t.c very clear. This shape of an object is due to its edges. So in blurring, we simple reduce the edge content and makes the transition form one color to the other very smooth.a) In your own words, briefly explain a blurred image and why it is sometimes useful to blur an image.EV(6)b) Distinguish between blurring and zooming in your own words and provide in each case practical examples.EV(5)c) Identify and describe the three common types of filters that are used to perform blurring by illustrating with appropriate examples.
Consider a North American traffic light. The light (Traffic Light #1) is red by default, and only turns green when a car is present at the red light, as sensed by the car presence sensor, and the light stays green as long as there is a car sensed. If a walker presses a button to request to cross the street, or if there are no cars present, the light turns yellow, and then red on the next clock trigger. The walk button has priority over the presence of a car, and the light will stay red when a walker presses the walk button. a. Draw the state machine diagram. The color of the light is the output of the system. b. Find Boolean expressions for the flip flop input equations and output equations
Please answer the following question in depth with full detail. Consider the 8-puzzle that we discussed in class. Suppose we define a new heuristic function h3 which is the average of h1 and h2, and another heuristic function h4 which is the sum of h1 and h2. That is, for every state s ∈ S: h3(s) =h1(s) + h2(s) 2 h4(s) =h1(s) + h2(s) where h1 and h2 are defined as “the number of misplaced tiles”, and “the sum of the distances of the tiles from their goal positions”, respectively. Are h3 and h4 admissible? If admissible, compare their dominance with respect to h1 and h2, if not, provide a counterexample, i.e. a puzzle configuration where dominance does not hold.
In class this week, we will work on simulating the game of Yahtzee. In the game of Yahtzee, five dice are tossed, and various combinations of numbers, similar to poker hands, are assigned point values. In the game, dice can be selected and re-tossed, but we will focus on calculating the probabilities for the first toss only. We will also deal only with the "lower half" of the score card in the game. For the interested student, continuing this project to account for the complete rules of play would be an entertaining challenge. Anyone not familiar with Yahtzee should try a web search for the rules of the game. Some sites have applets that let you play online. All you really need to know for this lesson, though, is which combinations are counted. We will call these "hands," as the combinations in poker are called. The hands in Yahtzee are: Three of a Kind (three of one number and two others that are different) Full House (three of one number and two of another number) Four of a Kind…
