We can implement requests to the waiter as either a queue of requests or as a periodic retry of a request. With a queue, requests are handled in the order they are received. Th e problem with using the queue is that we may not always be able to service the philosopher whose request is at the head of the queue (due to the unavailability of resources). Describe a scenario with 5 philosophers where a queue is provided, but service is not granted even though there are forks available for another philosopher (whose request is deeper in the queue) to eat.If we implement requests to the waiter by periodically repeating our request until the resources become available, will this solve the problem described in the above Exercise? Explain.

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,…
Correct answer will be upvoted else downvoted. Computer science.    Child Ehab has a piece of Cut and Stick with an exhibit an of length n composed on it. He intends to snatch some scissors and do the accompanying to it:    pick a reach (l,r) and cut out each component al, al+1, ..., ar in this reach;    stick a portion of the components together in a similar request they were in the exhibit;    end up with different pieces, where each piece contains a portion of the components and each component has a place with some piece.    All the more officially, he segments the arrangement al, al+1, ..., ar into aftereffects. He thinks a dividing is lovely if for each piece (aftereffect) it holds that, assuming it has length x, no worth happens rigorously more than ⌈x2⌉ times in it.    He didn't pick a reach yet, so he's pondering: for q ranges (l,r), what is the base number of pieces he really wants to parcel the components al, al+1, ..., ar into with the goal that the dividing is delightful.…
