- You are a detective in charge of bringing down drug dealers (D). A tip has led you to a small apartment complex where you believe one or more D might be hiding out. There are five apartments in a row. Each apartment could contain a drug dealer Dor could contain innocent people: adults (A), families with babies (B), or with teenagers (T). Before you break down a door, you need to be absolutely sure that a dealer D is inside, otherwise you could get sued for police sub-optimality. 1 2 3 4 5 m To help you narrow down where drug dealers D might be (if any are there at all!), you use the fact that different people make different noises. Every time you walk between two apartments, you can hear the louder of the two noises that are being made in those apartments. The loudest people are teenagers T, who blast music (m), the next loudest are babies B who cry (e), the next loudest is the drug dealer D, who makes a rustling sound (r), and the quietest people are adults A. who are totally silent…You have a backpack that can carry at most 15 kg of stuff (following image). There are ten boxes of five types (A, B, C, D, and E), with two boxes of each type. The weights and values of the boxes are given in the figure. You want to select some of these boxes to put in your backpack in order to maximize their total value, but you cannot exceed the backpack’s weight capacity. Additionally,• if a type B box is selected, then no type C box can be selected• at least one box of either type A or type D must be selected Formulate an integer linear programming model to help you make the bag packing decision. To assist you, below are your decision variables.• yi: select (= 1) or not select (= 0) type i box, i = A, B, C, D, E.• xj: The number of type j boxes selected, j = A, B, C, D, E.You have a fence post located at the point (x,y) where a goat is tethered by a rope. You also have a house, which is a rectangle with diagonally opposite corners at the points bottom-left: (x1,y1) and top-right: (x2,y2). You want to pick a length of rope that guarantees the goat cannot reach the house. Determine the minimum distance from the fence post to the house, so that you can make sure to use a shorter rope. Recall that the distance formula is: sqrt( (x2−x1)^2+(y2−y1)^2 ) The input consists of a single line containing six space-separated integer values: x, y, x1, y1, x2, and y2. You are guaranteed that x1<x2 and y1<y2, and that (x,y) is strictly outside the axis-aligned rectangle with corners at (x1,y1) and (x2,y2). Return the minimum distance from the goat’s post to the house as a floating-point value from main(). Learning Objectives Be able to create a program with a lesser template.

Each pharmacy sells several drugs and has a price for each. A drug could be sold at several pharmacies, and the price could vary from one pharmacy to another. Doctors prescribe drugs for patients. A doctor could prescribe one or more drugs for several patients, and a patient could obtain prescriptions from several doctors. Each prescription has a date and a quantity associated with it. You can assume that, if a doctor prescribes the same drug for the same patient more than once, only the last such prescription needs to be stored. Pharmaceutical companies have long-term contracts with pharmacies. A pharmaceutical company can contract with several pharmacies, and a pharmacy can contract with several pharmaceutical companies. For each contract, you have to store a start date, an end date, and the text of the contract. Pharmacies appoint a supervisor for each contract. There must always be a supervisor for each…Let's revisit our first problem, where we want to set up a series of chess matches so we can rank six players in our class. As we did before, we will assume that everyone keeps their chess rating a private secret; however, when two players have a chess match, the person with the higher rating wins 100% of the time. But this time, we are only interested in identifying the BEST of these six players and the WORST of these six players. (We don't care about the relative ordering or ranking of the middle four players.) Your goal is to devise a comparison-based algorithm that is guaranteed to identify the player with the highest rating and the player with the lowest rating. Because you are very strong at Algorithm Design, you know how to do this in the most efficient way. Here are five statements. A. There exists an algorithm to solve this problem using 6 matches, but there does not exist an algorithm using only 5 matches. B. There exists an algorithm to solve this problem using 7 matches,…Problem You have a fence post located at the point (x,y) where a goat is tethered by a rope.

He assigns some requirements about system that how should it work. The requirements are such a way that there are only '5' number of box office windows in the theatre. Each window can have at max '20' number of people waiting in line. To start with, only one window is opened. If the number of people waiting in line in that window exceeds 20, then the next window is opened and people can join the line in that window. Likewise, if both the first and second windows have n number of people waiting in each queue, then a third window is opened. This can go on until the maximum number of windows w is reached. Let us assume that once a window is opened it never closes. A new window is only opened if all open windows are full. Each person can buy only one ticket. So, the system should not allot more than one ticket per person. Let us assume that the system issues one ticket…You own a club on eerie planet. The day on this planet comprises of H hours. You appointed C crew members to handle the huge crowd that you get, being the best club on the planet. Each member of the crew has fixed number of duty hours to work. There can be multiple or no crew members at work at any given hour of the day. Being on weird planet, the rules of this club cannot be normal. Each member of the crew only allows people who are taller than him to enter the club when he is at work. Given the schedule of work and heights of the crew members, you have to answer Q queries. Each query specifies the time of entry and height of a person who is visiting the club. You have to answer if the person will be allowed to enter the club or not.

Each house is situated on a 2D plane, in a point with integer organizes. There may be various houses situated in a similar point. The chairman of the city is requesting you for places for the structure from the Eastern show. You need to track down the number of spots (focuses with integer arranges), so the outline distance from every one of the houses to the show is insignificant. The display can be inherent a similar point as some house. The distance between two focuses (x1,y1) and (x2,y2) is |x1−x2|+|y1−y2|, where |x| is the outright worth of x. Input First line contains a solitary integer t (1≤t≤1000) — the number of experiments. The principal line of each experiment contains a solitary integer n (1≤n≤1000).
