Pass the string and string length as parameters. A member of the power set can therefore be described by a binary number, such that the subset contains only those elements of the set corresponding to a 1 in the binary value. For example, java -Xmx128 BigApp java. using System; public class GfG { / Function to count subsets such that all / subsets have distinct elements. Approach: This problem is quite similar to Print All Subsets of a given set. One approach would be to use recursion to create the subsets and stop the recursion when the sum of the elements omitted from the original set is greater than total-k, where total is the sum of all elements of the array. Use the first for loop to select the starting index of the subset. Java 8 introduced the Stream API that provides several useful methods.
