A chest of drawers, also called a dresser or a bureau, is a type of cabinetthat has multiple parallel, horizontal drawers generally stacked one aboveanother (See Figure 1). Each drawer has a lock to secure any propertyinside, but sometimes a drawer may not be secure even when it is locked.For instance, imagine a scenario where the second drawer from the top islocked, but the top drawer is not. In such a case, a burglar can access thesecond drawer by opening the top drawer and gaining access to the propertyinside the second drawer.Given the number of drawers, n, and the number of secure drawers, k.You can assume that nk. Write an O (nk) algorithm to find a number ofways to ensure that exactly k drawers are secure. For example, the numberof drawers n = 6, and number of secure drawers k = 4. The output is 6(ULLLLL, LULLLL, LLULLL, LLLULL, LLLLUL, and LLLLUU).FIGURE 1. Chest of Drawers

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
In the famous dining philosophers problem, a bunch of philosophers aresitting around a circular table with one chopstick between each of them. A philosopher needsboth chopsticks to eat, and always picks up the left chopstick before the right one. A deadlockcould potentially occur if all the philosophers reached for the left chopstick at the same time. Usingthreads and locks, implement a simulation of the dining philosophers problem that prevents deadlocks.
A safe is locked by a combination of of four binary digits (that is, 0 or 1), but theowner has forgotten the combination. The safe is designed in such a way that nomatter how many digits have been pressed, if the correct combination of three digitsis pressed at any point, then the safe automatically opens (there is no ”enter” key).Our goal is to find the minimum number of digits that one needs to key in in order toguarantee that the safe opens. In other words, we wish to find the smallest possiblelength of a binary sequence containing every four-digit sequence in it.(a) Create a digraph whose vertex set consists of three-digit binary sequences. Fromeach vertex labelled xyz, there is one outgoing edge (labelled 0) leading to vertexyz0, and another outgoing edge (labelled 1) leading to vertex yz1.(b) Explain why every edge represents a four digit sequence and why an Euleriantour of this graph represents the desired sequence of keystrokes.(c) Find the minimum number of digits that one…
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…

Telemedicine is the ability to provide medical assistance from a distance using telecommunication. For this example, imagine that a platoon of soldiers might be out in the battlefield. While a medic might be with them, he/she cannot constantly monitor each soldier’s vital signs, but if various sensors were sewn into soldier uniforms, vital statistics could be monitored from a distance by a doctor at headquarters. That doctor may be able to identify a medical problem for one of the soldiers and relay that information and instructions for care back to a medic in the area. The doctor at headquarters should be able to select a given soldier and see that soldier’s vital signs on a portable computer device (e.g., iPad). Perhaps the medic in the field might even have a video camera so that the doctor may be able to view a wound. Design the interface that the HQ doctor would see. Using the display design principles design an interface mockup using graphics, photos, and/or text to show what…
Mastermind is a code-breaking game for two players. In the original real-world game, one player A selects 4 pegs out of 6 colors and puts them in a certain fixed order; multiples of colors are possible (for example, red-green red-green). His opponent B does not know the colors or order but has to find out the secret code. To do so, B makes a series of guesses, each evaluated by the first player. A guess consists of an ordered set of colors which B believes is the code. The first player A evaluates the guess and feeds back to B how many positions and colors are correct. A position is correct ("black") if the guess and the secret code have the same color. Additional colors are correct ("white"), if they are in the guess and the code, but not at the same location. For example1 2 3 4secret: red-green red greenguess: red blue green purpleresults in one correct position ("black = 1") for the red peg at position one and one additional correct color ("white=1") for the green peg in the guess.…

The language for coding must be in python Neural Network Units Implement a single sigmoid neural network unit with weights of [-1.2, -1.1, 3.3, -2.1] Calculate the outputs for two training examples:Example 1: [0.9, 10.0, 3.1, 1]Example 2: [0.9, 2.1, 3.7, 1] Note that you don't have to explicitly include a threshold or bias since the examples include a last element of 1 which means that the last weight effectively operates as a threshold. Assuming that a sigmoid unit response >0.5 denotes a positive class and <0.5 is negative class, is example 1 positive or negative? is example 2 positive or negative? Create a single ReLU unit and provide the outputs for those examples. Calculate the derivative of the sigmoid with respect to net input for both examples Calculate the derivative of the ReLU with respect to net input for both examples
