Patientsare free to use any dental office but, naturally, must makeappointments in advance. A record of all such appointments iskept which specifies the patient’s name, the date and time ofthe appointment and a list of services performed. Adultpatients have a SIN (Social Insurance Number) but theirchildren typically do not. Each office provides specific services(e.g. cleaning, filling, X-rays, extraction, etc.) to the patients andbills them accordingly. Performing certain services consumessupplies (e.g. floss, amalgam, X-ray film, etc.). Such suppliesare purchased from a variety of suppliers each of whom isidentifiable by a unique supplier code.

The Driver enters constraints for a trip as a sequence of destinations. 2. Based on a database of maps, the planning service computes the shortest way of visiting the destinations in the specified order. The result is a sequence of travel segments concatenated together and a list of directions. 3. The Driver can revise the trip by adding or removing destinations. Exit condition The Driver saves the planned trip by name in the planning service database for later retrieval..

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,…Provide examples to illustrate your ability to differentiate between physical and schematic representations.Give examples to demonstrate your understanding of how to distinguish between physical and schematic models

There were m members numbered from 1 to m, who contended on a problemset of n issues numbered from 1 to n. Presently the article is going to happen. There are two issue creators, every one of them will tell the instructional exercise to precisely k back to back errands of the problemset. The creators pick the section of k continuous errands for themselves autonomously of one another. The sections can correspond, meet or not cross by any means. The I-th member is keen on paying attention to the instructional exercise of all continuous errands from li to ri. Every member consistently decides to pay attention to just the issue creator that tells the instructional exercises to the most extreme number of assignments he is keen on. Leave this greatest number alone artificial intelligence. No member can pay attention to both of the creators, regardless of…Correct answer will be upvoted else downvoted. Computer science. You are given an undirected complete diagram with n hubs, where a few edges are pre-appointed with a positive weight while the rest aren't. You wanted to allot all unassigned edges with non-negative loads so that in the subsequent completely appointed total chart the XOR amount, all things considered, would be equivalent to 0. Characterize the offensiveness of a completely alloted complete chart the heaviness of its base spreading over tree, where the heaviness of a crossing tree approaches the amount of loads of its edges. You really wanted to appoint the loads with the goal that the offensiveness of the subsequent chart is just about as little as could be expected. As an update, an undirected complete diagram with n hubs contains all edges (u,v) with 1≤u<v≤n; such a chart has n(n−1)2 edges.

Computer science. every subject (aside from precisely one), there exists an essential theme (for the point I, the essential point is pi). Ivan can't give a talk on a subject prior to giving a talk on its essential theme. There exists no less than one substantial requesting of themes as per these essential imperatives. Requesting the subjects effectively can assist understudies with understanding the talks better. Ivan has k uncommon sets of points (xi,yi) with the end goal that he realizes that the understudies will comprehend the yi-th subject better if the talk on it is led just after the talk on the xi-th theme. Ivan needs to fulfill the requirements on each such pair, that is, for each i∈[1,k], there should exist some j∈[1,n−1] to such an extent that qj=xi and qj+1=yi. Presently Ivan needs to know whether there exists a requesting of subjects that fulfills this multitude of imperatives, and if something like one exists,…
