Complexity Analysis: Time Complexity: O(sum*n), where sum is the âtarget sumâ and ânâ is the size of array. //add empty set Problem: Subsets. Best Time to Buy and Sell Stock with Transaction Fee. Backtracking For example, If S = [1,2,3], a solution is: The solution set must not contain duplicate subsets. Subsets II: Given a collection of integers that might contain duplicates, nums, return all possible subsets (the power set). for (int j = 0; j < result.size(); j++) { //get existing sets If you had some troubles in debugging your solution, please try to ask for help on StackOverflow, instead of here.
