c program for optimal merge pattern using greedy method

Further analysis may include studying any potential errors or bugs associated with certain implementation techniques or coding styles. Then, analysts analyze how each step works together with other components within the program in order to ensure that it runs as intended. The process begins with choosing an appropriate algorithm from a set of known algorithms based on its complexity and efficiency. The goal of design and analysis is to create an efficient algorithm, or series of steps, that can be used to solve a given problem in the most effective way possible.Īnalysts identify which operations are necessary for solving the problem, determine the data structures required, then design a sequence of steps needed to achieve the desired outcome. What is the design and analysis of algorithms?ĭesign and analysis of algorithms is an important field of computer science that focuses on the study of efficient ways to solve a problem. Design and analysis of algorithms mcq with answers pdf unit 1. Just the obvious fact that if the records are unique (which is safe to assume), the set bit count always increases.Design and Analysis of Algorithms Objective Questions and Answers pdf for the preparation of MCA, BCA and other IT examinations. I've also tried playing around with set bit counts, but I've found no meaningful results. The sub-optimal overhead gets bigger as the list size increases. For a list with 250 items where the correct solution is 14, the average size computed by greedy merging is about 30 (varies from 20 to 70). The greedy approach is usually misleading in similar cases and so it is for this problem, but I can't find a simple counterexample that'd lead to a correct solution. In other words, if two values of two triplets are equal, remove these two triplets, bitwise OR the third values and place the result to the collection. For two triplets (A, B, C) and (A', B', C'), remove the original triplets and place the triplet (A | A', B, C) if B = B' and C = C', where | is bitwise OR.To do this, we're provided a simple rule that allows us to merge the triplets :

The goal is to minimize the size of the collection. The value stored inside can be big, so generally it's impossible to create an array of size A, B, or C. I've got a collection of triplets of integers - let's call these integers A, B, C. I'm trying to come up with an algorithm for the following problem :
