This cupboard contains 4 inputs which is the switch, brightness, temperature, and the door. We assume that the sensors are available as mentioned. This closet then has 3 outputs, which is the light, perfume and fan. The output will function on specified conditions. The fan is used to improve air-circulation in the cupboard and afterward become the dryer of the cupboard. The function of the perfume is to ensure that the clothes have an everlasting nice smell while the light is to enable us to use the closet in the dark. Notice that fan and light will operate when switch is on but the perfume will operate regardless the switch is on or not because it uses the battery as power supply.

You are trapped in a room. There are n consecutive doors in front of you, with each door being behind the previous door. You need to open all doors to escape. In the same room, there are n switches and each switch connects to a different door. However, you don't know which switch connects to which door AND for some doors the "up" position will close the door while for other doors the "down" position will open the door. You will need to place all n switches in the correct configuration to escape. You can set the switches in any configuration and walk over to check which is the first closed door (since the doors are consecutive, you can't see the status of the doors behind the first closed one). What is an algorithm that will find the correct configuration to open all doors within O(n log n) trials?

You have 1000 bottles of soda, and exactly one is poisoned. You have 10 test strips whichcan be used to detect poison. A single drop of poison will turn the test strip positive permanently.You can put any number of drops on a test strip at once and you can reuse a test strip as many timesas you'd like (as long as the results are negative). However, you can only run tests once per day andit takes seven days to return a result. How would you figure out the poisoned bottle in as few daysas possible?Follow up: Write code to simulate your approach
Reimplement the TrafficLight class using a simple counter that is advanced in each call to next. If the traffic light was initially green, the counter has values 0 1 2 3 4 5 6 ... . If the traffic light was initially red, the counter has values 2 3 4 5 6 7 8 ... . Compute the current color and the number of reds, using integer division and remainder.
The fairies in Fairyland are getting ready to compete in the Fly High game where the fairy that flies the highest isdeclared a winner. The number of fairies participating in this competition is not known ahead of time. Before flyinghigh, each fairy goes through a pixie dust machine and gets sprinkled with the pixie dust. The pixie dust allows themto fly and perform their special talent high up in the sky. Pixie dust can be of any one of the 4 colours (red, blue,yellow, and green) and each colour has a dust strength in the following ranges (dust strength determines roughlyhow high a fairy can fly):Colour StrengthRed 40 - 49Blue 30 - 39Green 20 - 29Yellow 10 - 19Write a Python program, in a file called fairyland.py, to include the following functions:• function main that repeatedly obtains a fairy’s name (from the user) and, using other functions, determinesthe colour of pixie dust that the fairy has been dusted with, the height of the fairy’s flight (based on thatcolour), and keeps…
A robot starts on a point marked “A” on a rectangular grid of points. The starting point is always the top left point on the grid. The robot can move left, right, up or down, moving from one point to the next. By moving in steps going left, right, up or down, the robot would like to reach a point marked “B”, which is always the bottom right point in the grid. Sometimes, points are marked as “x”, and the robot is not allowed to visit them at all. A robot is never allowed to visit a point more than once. In how many ways can the robot move from A to B and visit all points along the way? For example, in the following grid, represented in text as A . . . . B there is only one path from A to B: In the following grid, represented in text as A . . x x B there is still only one path (we're lucky because of the two x's): However, in the grid A . . . x B there are no ways for the robot to move from A to B and visit all points that are not marked with “x”. Write a single…

A logical step forward from interactive animated programs is games. The goal of this assignment is to program the classic computer game, Snake. The goal of Snake is to create a snake as long as possible. This is achieved by guiding the snake to an apple on the game board. The snake cannot stop moving, and dies whenever it hits something (excluding apples). Because the snake is growing longer and longer as the game progresses, it gets increasingly difficult to avoid collisions with the snake itself. The player can change the direction of the head of the snake by using the arrow keys. At step in the game, there is always an apple somewhere on the board. If the snake eats an apple, the snake becomes one cell longer. A new apple is placed on a random location, excluding all places covered by the snake. When the snake reaches a side of the game board, it re-emerges at the opposite end. It is probably easiest to understand the game by playing it yourself. You can find a lot of snake…
Read the following scenario: To implement an exam, an instructor first notifies the students of the exam date and the topics to be covered. The instructor will prepare the exam paper, gets it copied to produce enough copies for the class, and hands it out to students at the designated time and location. The students attempt their answers to exam questions and hand in their answer papers to the instructor. The instructor then gives the answer papers to the tutor, along with sample solutions to each question, and gets them to mark it. The tutor will then records all the marks and return the answer papers to the students. After the answer papers have been returned to the students, they can raise any issues or queries about the marks they received. The instructor then reviews these queries/issues and decides whether marks adjustments are needed. If there are marks adjustments, the instructor will request the tutor to make the necessary changes in the marks record. Draw a sequence diagram…
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.

A platform has space for at most n people at any one time. People are only admitted when the number of persons on the platform does not exceed the limit. Using a semaphore write a JAVA class that could be used to control automated access to the platform. Your class must keep a record of the number of people on the platform at any given point in time and must make this value visible through a public method count()
Question # 06: The typical Computer Screen has a WIMP Setup. Most Common WIMP arrangements work on the basis of a Desktop metaphor, in which common actions are linked to similar actions in the real world. For Example, moving a File is achieved by selecting and dragging it into a relevant folder or filing Cabinet. Give Two Examples with explanation of the actions with their Real world Equivalents.
