The divide-and-conquer paradigm often helps in the discovery of efficient algorithms. It is done only by insertion sort because in insertion sort we compare the one card to another all inserted card. xt = ? c 2- The frequency needed to produce tetanus: a- is increased by cooling. Which of the following statements is TRUE? Which of the following algorithms exhibits the unnatural behaviour that, minimum number of comparisons are needed if the list to be sorted is in the reverse order and maximum number of comparisons are needed if they are already in sorted order? 6. The fourth section includes the advanced topics such as transform and conquer, decrease and conquer, number thoeretics, string matching, computational geometry, complexity classes, approximation algorithms, and parallel algorithms. The solved questions answers in this Divide And Conquer (Basic Level) - 1 quiz give you a good mix of easy questions and tough questions. The naive solution for this problem is to calculate sum of all subarrays starting with every element and return the maximum of all. If number of swapping is the measure of efficiency of algorithm the selection sort is best since it cannot take swap more than O(n). Given a set of n positive integers, S = {a1 ,a2 ,a3 ,…,an} and positive integer W, is there a subset of S whose elements sum to W? We are given two sequences X[m] and Y[n] of lengths m and n respectively, with indexes of X and Y starting from 0. Decrease-and-Conquer. ...

So insertion sort should be preferred. Since the length of given strings A = “qpqrr” and B = “pqprqrp” are very small, we don’t need to build a 5x7 matrix and solve it using dynamic programming. MULTIPLE-CHOICE QUESTIONS Complete these questions without using the text and then refer back. break; The structure within a cell that is concerned with energy is: (a) the cytoplasm, (b) the cell membrane, (c) the nucleus, (d) the mitochondrion. On solving, T(n) = 1.5n - 2. 2 Divide-and-Conquer We use quicksort as an example for an algorithm that fol-lows the divide-and-conquer paradigm. divide-and-conquer decrease and conquer. “qprr”, “pqrr” and “qpqr” are common in both strings. For example, mergesort uses divide and conquer strategy. Q. greedy nature. Since there is no subsequence , we will now check for length 4. Decrease and conquer is also known as _____ approach. So, option (b) can’t be a valid output. Which of the following standard algorithms is not Dynamic Programming based. â¦ Rather we can solve it manually just by brute force. switch (opcode) Divide-and-conquer as breaking the problem into a small number of pivot Sieve .

Reduce problem instance to smaller instance of the same problem 2. fb = f(xb) // function value at new xb, end while You want to check whether a given set of items is sorted. Question 2 Explanation: In quick sort, the array is divided into sub-arrays and then it is sorted (divide-and-conquer strategy). int main() If p = 10, q = 100, r = 20, s = 5 and t = 80, then the number of scalar multiplications needed is. Which of the following sorting methods sorts a given set of items that is already in sorted order or in reverse sorted order with equal speed? Quicksort Multiple choice Questions and Answers (MCQs) ... Quick sort follows Divide-and-Conquer strategy. Algorithm A2 can compute min-max in a2 comparisons by scanning the array linearly. Here, A1 is a 10 × 5 matrix, A2 is a 5 x 20 matrix, and A3 is a 20 x 10 matrix, and A4 is 10 x 5. If there are many such indices, the algorithm can return any one of them. MCQs to test the knowledge acquired have also been included. If they are small enough, solve the sub-problems as base cases. In the above question, which entry of the array X, if TRUE, implies that there is a subset whose elements sum to W? // intermediate value If we get the entry X[n, W] as true then there is a subset of {a1, a2, .. an} that has sum as W. A sub-sequence of a given sequence is just the given sequence with some elements (possibly none or all) left out. break; a) Brute force d) Transform-and conquer b) Divide-and-conquer e) None of the above c) Decrease-and-conquer 27. We get minimum number of multiplications using ((M1 X (M2 X M3)) X M4). Aptitude test Questions answers . The following partially given function in the C programming language is used to find the kth smallest element in an array a[ ] of size n using the partition function. When multiplied as (((M1 X M2) X M3) X M4), the total number of scalar multiplications is pqr + prs + pst. Consider two strings A = "qpqrr" and B = "pqprqrp". You should prefer. Initialize Ln−1=1 Either the problem or algorithm can be transformed in one of three ways: Instance simplification: the instances of the problem can be transformed into an easier instance to solve. write “return xb” Solve smaller instance 3. View the answer of each MCQ by clicking over the Show/Hide Answer or all answers at the bottom of the page. The algorithm uses dynamic programming paradigm, The algorithm has a linear complexity and uses branch and bound paradigm, The algorithm has a non-linear polynomial complexity and uses branch and bound paradigm, The algorithm uses divide and conquer paradigm. if (left_end+1==k) Then, The number of scalar multiplications required in the following sequence of matrices will be : A1((A2A3)A4) = (5 x 20 x 10) + (5 x 10 x 5) + (10 x 5 x 5) = 1000 + 250 + 250 = 1500. All other are dynamic programming based. stkFunc (0, 10); 73. Computer Science Engineering (CSE) A binary search tree contains the values -1, 2, 3, 4, 5, 6, 7 and 8. 2.
