WebOct 9, 2024 · Given an array arr[] of non-negative integers and an integer sum, the task is to count all subsets of the given array with a sum equal to a given sum. Example 1: … WebJan 10, 2024 · For each of the new subsets created in 2.i using A[i], let sum be the sum of the elements in the subset, and count be the number of elements in the subset. If count == K AND (sum <= L OR sum >= R) then increment the global_counter. If count < K, insert the newly created subset into the list. Return the global_counter.

We need to find the number of subsets whose … WebMay 30, 2024 · If i is out of bounds or sum is negative, then there is no subsets that sum to the given sum starting past i, so we return 0. If the sum is equal to 0, then there is only one subset of arr that equals sum which is the empty subset (assuming arr elements are strictly positive. If arr can include 0s, then this is a totally different problem). how to install a wood stove thimble
Count number of subsets whose sum is greater than or equal to k
WebDec 27, 2024 · An efficient solution is to use the fact that every element of the set is present in exactly 2^(n-1) subsets. Here, in this solution, first, check whether the given value X is present in a given set of elements or not. If X is present, then compute and return 2^(n-1), (using modular exponentiation to compute power 2^n-1). Otherwise, return 0.
