As a teaching aministr of the department, your responsibility is to schedule the classes for a particular classroom. Suppose there are n classes, each class i is represented by its start time and finishing time [S, f], and we say that two classes i and j are non-conflicting if they do not overlap in time (i.e., s2fj or s2f). You want to schedule as many classes for the classroom as possible, but the scheduled classes should be non-conflicting. Develop an algorithm so that you can select the maximum number of classes for the classroom. (We are expecting either pseudocode or language description of your algorithm)

- You are organizing a conference that has received n submitted papers. Your goal is to get people to review as many of them as possible. To do this, you have enlisted the help of k reviewers. Each reviewer i has a cost sij for writing a review for paper j. The strategy of each reviewer i is to select a subset of papers to write a review for. They can select any subset S; C {1,2, ..., n}, as long as the total cost to write all reviews is less than T (the time before the deadline): 2 Sij 1. (b) Show that for B = 2 this fraction is close to 1/3. [Hint: You can consider an instance with 3n + 1 papers and only n will be reviewed.]Computer science. Correct answer will be upvoted else downvoted. Development of the exhibit in William's cell machine happens iteratively in the accompanying manner: In the event that the component is dead and it has precisely 1 alive neighbor in the present status of the exhibit, then, at that point, on the following emphasis it will become alive. For a component at list I the neighbors would be components with files i−1 and i+1. In case there is no component at that list, it is viewed as a dead neighbor. William is a sympathetic individual so all alive components stay alive. Check the note area for instances of the advancement. You are given some underlying condition, everything being equal, and you really wanted to help William discover the condition of the cluster after m emphasess of advancement. Input Each test contains various experiments. The principal line contains the number of experiments t (1≤t≤103). Depiction of the experiments follows. The primary…This question is related to System Models. A navigation system is to be developed to help the delivery riders to deliver food to their customers. You are asked to design the UML Class Diagram for the system based on the following: A navigation device belongs to only one rider's vehicle. A navigation device can calculate at least zero route. In return, every route can be calculated by many navigation devices. A route has at least one road segment, and every road segment belongs to many routes. A road segment is defined by road name as well as start and end points. "Navigation device with congestion avoiding" is a specialization of the navigation device, and it queries many traffic jam information. Your diagram must include any related relationships i.e. generalization, aggregation and/or composition and multiplicity.
- We wish to implement a system that allows the management of Employees and Students. As a first step. you need to implement the above UML diagrams Notes: . ZOOM . PERSON, EMPLOYEE and STUDENT should be public static constants The no-arg constructor will initialize ID, firstName and lastName to their respective null values. It will set personType to PERSON, and sortorder to LAST_NAME The overloaded constructor will assign each parameter to its respective field. sortorder will also be set to LAST_NAME toString() will output type, ID, firstName and lastName, all tab separated. This is an override method equals() will compare if the current object and the parameter contain the same values. This is an override method compareTo() compares the current object and the parameter. This is an override method. It will be used to sort objects Needs the Comparable interface O Will only compare fields depending on the sortorder. For example, if the sortorder is TYPE, it should then compare the…Consider the following scenario:You are required to design and implement a system that will be used to take online exams. There are two main groups of users, teachers, and students. Teachers can schedule exams and add students by their email addresses. The teacher should also be able to create student groups. Student groups can be comprised of other student groups. Teachers, if they so wish, can add students to an exam by adding individual students, and/or groups. Half an hour before the scheduled time of the exam, the students should get a notification via email.Exam assessment is done on a per-question level. For each question, the teacher can set one out of many assessment methods (e.g. content-matching, MCQ, mathematical correctness, manual marking, etc.), with each method having its own parameters as specified by the teacher. Certain questions can have nested questions. When an assessment method is set for these, the teacher should be given the choice to apply the same assessment…Correct answer will be upvoted else Multiple Downvoted. Computer science. You need to change this grouping so all components in it are equivalent (I. e. it contains a few events of a similar component). To accomplish this, you pick some integer x that happens to some extent once in a, and afterward play out the accompanying activity quite a few times (perhaps zero): pick some portion [l,r] of the arrangement and eliminate it. Yet, there is one special case: you are not permitted to pick a fragment that contains x. All the more officially, you pick some adjoining aftereffect [al,al+1,… ,ar] to such an extent that ai≠x if l≤i≤r, and eliminate it. After expulsion, the numbering of components to one side of the eliminated portion changes: the component that was the (r+1)- th is presently l-th, the component that was (r+2)- th is currently (l+1)- th, etc (I. e. the leftover arrangement simply falls). Note that you can not change x after you picked it. For instance, assume n=6,…
- In Python Programming language USING AVL TREE Building an automatic appointment reservation system for a very busy heart surgeon in the city. The system is going to work as follows: The patient requests for an appointment time. The system looks through the list of appointments and if there are no appointments scheduled within 10 minutes either way of the requested time, then that appointment is added to the list of appointments along with the patient ID. Otherwise, the patient is given the next available time automatically that is not within 10 minutes of any other scheduled appointment. At the appointed time, the appointment is marked as serviced and deleted from the list of appointments. You must use an AVL Tree to implement this appointment system. The reservation system should run as follows: It should run for a total of 12*25*60 minutes. At each time instant, there is a 10% probability that a new request comes in. If a new request comes in, generate a random number between the…A transaction database is a set of transactions completed in a supermarket database. Each transaction is a set of items. For example, consider the following transaction database. It contains 5 transactions (t1, t2, ..., t5) and 5 items (1,2, 3, 4, 5). For example, the first transaction represents the set of items 1, 3 and 4. It is important to note that an item is not allowed to appear twice in the same transaction and that items are assumed to be sorted by lexicographical order in a transaction. Transaction id Items t1 {1, 3, 4} t2 {2, 3, 5} t3 {1, 2, 3, 5} t4 {2, 5} t5 {1, 2, 3, 5} What is the output of the Apriori algorithm run on the previous transaction database with a minimum support of 40 % (2 out of 5 transactions)?Create a UML class diagram for the following problem: In a garage, there may be several vehicles.

Each event has a time stamp that denotes the time when the event will occur. The simulation program needs to efficiently perform the following two fundamental operations: • Insert an event with a given time stamp (that is, add a future event). • Extract the event with smallest time stamp (that is, determine the next event to process). Question 3 3.1 Which data structure should be used for the above operations? Why? 3.2 Write an application that adds the following time stamp in the selected data structure. Event1 occurs at 12:00:54 Event2 occurs at 10:40:54 Event3 occurs at 11:30:45 Event4 occurs at 12:00:00 3.3 Write a method that extracts the smallest time stamp. 3.4 What is the maximum running timeCorrect answer will be upvoted else downvoted. Computer science. You are permitted to alter the marks through the accompanying activity: Pick two particular integers I and j among 1 and n. Trade the marks of focuses I and j, lastly Draw the section between focuses I and j. A grouping of tasks is legitimate if in the wake of applying every one of the activities in the succession all together, the k-th point winds up having the name k for all k among 1 and n comprehensive, and the drawn sections don't meet each other inside. Officially, assuming two of the portions cross, they should do as such at a typical endpoint of the two sections. Specifically, all drawn portions should be unmistakable. Track down any legitimate arrangement of activities, or say that none exist. Input The main line contains an integer n (3≤n≤2000) — the number of focuses. The I-th of the accompanying n lines contains three integers xi, yi, man-made intelligence (−106≤xi,yi≤106,…
