Webstandard input. output. standard output. You are given two integers n and k. You are asked to choose maximum number of distinct integers from 1 to n so that there is no subset of chosen numbers with sum equal to k. A subset of a set is a set that can be obtained from initial one by removing some (possibly all or none) elements of it. WebSep 6, 2024 · Greedy Method. A greedy algorithm is an algorithm that follows the problem solving met heuristic of making the locally optimal choice each stage with the hope of finding the global optimum. The greedy method is a powerful technique used in the design of algorithms. Almost all problems that come under this category have 'n' inputs. impact professional solutions ltd
