. 6.Implement and simplify f (A, B, C, D) = Σ(1,3,5,8,9,11,13,15) using K-map?
A quadratic function f(x) is hidden from view. You must find the minimum value of the function f(x). Choose the form of the quadratic function f(x) that you would like to see in order to answer the question most efficiently. Form: Vertex Form ,f(x)=(x-3)^(2)-25
Q3. Compute the cost of r JOINA=B s using the method of index loops with an index of height 2 on B of s. Do the computation for the clustering index case. Assume that r occupies 4,000 blocks with 20 tuples per block, s occupies 10,000 blocks with 5 tuples per block, and the amount of main memory available is 402 blocks. Assume that at most 5 tuples in s match each tuple in r.

- I am trying to solve the teque kattis problem. Currently i have implemented a TailedLinkedList to push_back(), push_front() and push_middle() with O(1) time complexity, but my get() method is still running on O(n). Is there any way to retrieve an element from list in O(1) time?arrow_forwardSereja likes to hang around trees. A tree is an undirected graph on N vertices with N-1 edges and no cycles. Sereja has his own peculiar way of comparing two trees. To describe it, let's start with the way Sereja stores a tree. For every tree, Sereja has a value V– the root of the tree, and for every vertex i, he has an ordered list Q[i] with L[i] elements – Q[i][1], Q[i][2], ..., Q[iLI] which are children of the vertex i. Sereja assumes two trees to be equal if their roots are the same and for every i, the ordered list Q[i] is the same in both the trees that Sereja compares. So if Sereja has tree#1 given as [V=1, Q[1]=[2, 3], Q[2]=[], Q[3]=0] and tree#2 given as [V=1, Q[1]=[3, 2], Q[2]=[], Q[3]=[]], they will be considered different because Q[1] in the first tree is not equal to Q[1] in the second tree. For any vertex İ, Sereja calls number of vertices adjacent to it as E[i). Given an array C of N elements, Let f(C) be the number of different trees (in Sereja's representation) such…arrow_forwardSuppose we have an array A of n distinct elements. We will show that any BST T containing all elements in A can be converted into any other BST R containing all elements in A using O(n) rotations. (Recall that there may be many valid BST configurations (shapes) for a given data set.) (a) In a few sentences, explain how you can apply O(n) right rotations on T such that the resulting tree is only a single path (i.e., a straight line from the root to the rightmost possible leaf; this is called the right spine). In a right spine, every node except the root and some of the leaves is a right child. (b) Say we want to transform the new tree back into T. What would we do? (c) Using your answers to the above questions, design an algorithm to trans- form any tree T into any other tree R in O(n) time.arrow_forward
- Correct answer will be upvoted else downvoted. Computer science. It might have been a simple undertaking, yet it worked out that you ought to observe a few guidelines: Before all else, you select any sure integer x. Then, at that point, you do the accompanying activity n times: select two components of cluster with total equivalents x; eliminate them from an and supplant x with limit of that two numbers. For instance, if at first a=[3,5,1,2], you can choose x=6. Then, at that point, you can choose the second and the third components of a with total 5+1=6 and toss them out. After this activity, x equivalents 5 and there are two components in cluster: 3 and 2. You can toss them out on the following activity. Note, that you pick x before the beginning and can't transform it as you need between the activities. Decide how could you act to toss out all components of a.

That is, the DFAs are map 1-to-1 with respect to their nodes. Therefore, the DFAs arearrow_forward
- Correct answer will be upvoted else downvoted. We will consider cells of a square network n×n as contiguous in the event that they have a typical side, that is, for cell (r,c) cells (r,c−1), (r,c+1), (r−1,c) and (r+1,c) are nearby it. For a given number n, build a square lattice n×n to such an extent that: Every integer from 1 to n2 happens in this network precisely once; On the off chance that (r1,c1) and (r2,c2) are contiguous cells, the numbers written in them should not be neighboring. Input The principal line contains one integer t (1≤t≤100). Then, at that point, t experiments follow. Each experiment is characterized by one integer n (1≤n≤100). Output For each experiment, output: - 1, if the necessary network doesn't exist; the necessary lattice, in any case (any such network if a significant number of them exist).arrow_forwardLet A, B, C, D be the vertices of a square with side length 100. If we want to create a minimum-weight spanning tree to connect these four vertices, clearly this spanning tree would have total weight 300 (e.g. we can connect AB, BC, and CD). But what if we are able to add extra vertices inside the square, and use these additional vertices in constructing our spanning tree? Would the minimum-weight spanning tree have total weight less than 300? And if so, where should these additional vertices be placed to minimize the total weight? Let G be a graph with the vertices A, B, C, D, and possibly one or more additional vertices that can be placed anywhere you want on the (two-dimensional) plane containing the four vertices of the square. Determine the smallest total weight for the minimum-weight spanning tree of G. Round your answer to the nearest integer.
