- Correct answer will be upvoted else Multiple Downvoted. Computer science. Polycarp accepts that a bunch of k sections is acceptable in case there is a fragment [li,ri] (1≤i≤k) from the set, with the end goal that it converges each portion from the set (the convergence should be a point or section). For example, a bunch of 3 fragments [[1,4],[2,3],[3,6]] is acceptable, since the portion [2,3] meets each section from the set. Set of 4 fragments [[1,2],[2,3],[3,5],[4,5]] isn't acceptable. Polycarp ponders, what is the base number of sections he has to erase so the remaining portions structure a decent set? Input The primary line contains a solitary integer t (1≤t≤2⋅105) — number of experiments. Then, at that point, t experiments follow. The primary line of each experiment contains a solitary integer n (1≤n≤2⋅105) — the number of portions. This is trailed by n lines depicting the fragments.

So the constraints are:t_(l)+3<=t_(o),t_(l)+3<=t_(m),t_(l)+3<=t_(n)Task t can't start until tasks m and n are finished. Therefore:t_(m)+1<=t_(t),t_(n)+2<=t_(t),Task s can't start until tasks o and t are finished. Therefore:t_(o)+3<=t_(s),t_(t)+3<=t_(s)arrow_forward

- Suppose we have the following undirected graph, and we know that the two bolded edges (B-E and G-E) constitute the global minimum cut of the graph. 1. If we run the Karger’s algorithm for just one time to find the global minimum cut, what is the probability for the algorithm to find the minimum cut correctly? Please show your reasoning process. 2. How many times do we need to run the Karger’s algorithm if we want to guarantee that the probability of success is greater than or equal to 0.95, by “success” we mean that there is at least one time the Karger’s algorithm correctly found the minimum cut.

Describe, in pseudocode, how you would find all matching pairs of nuts and bolts. You need to find one solution for each of the problem-solving approaches given below. For each of your solution, determine how many comparisons of pairs of nuts and bolts you might have to make in the best- and worst- case scenario. You can assume that there are complete pairs, no single nuts or bolts, and that for each bolt, there is exactly one nut that fits. Describe a solution to the nuts and bolts problem (in pseudocode) using a Divide and Conquer Approach.arrow_forwardImagine that you have a problem P that you know is N P-complete. For this problem you have two algorithms to solve it. For each algorithm, some problem instances of P run in polynomial time and others run in exponential time (there are lots of heuristic-based algorithms for real N P-complete problems with this behavior). You can’t tell beforehand for any given problem instance whether it will run in polynomial or exponential time on either algorithm. However, you do know that for every problem instance, at least one of the two algorithms will solve it in polynomial time. (a) What should you do? (b) What is the running time of your solution? 564 Chap. 17 Limits to Computation (c) What does it say about the question of P = N P if the conditions described in this problem existed?arrow_forward
