Combination Sum II: Given a collection of candidate numbers (C) and a target number (T), find all unique combinations in C where the candidate numbers sums to T. Each number in C may only be used once in the combination. We can calculate the hash as we move down the stack. Find the k th largest element in an unsorted array. if input[index]+sum 4. = 30! 39. to refresh your session. Given a set of candidate numbers (candidates) (without duplicates) and a target number (target), find all unique combinations in candidates where the candidate numbers sums to target.

Platform to practice programming problems. This problem is an extension of Combination Sum. $\endgroup$ – marcamillion Jun 22 '12 at 8:37 2 $\begingroup$ 1) I substracted $\binom{5}{0}=1$ to use the formula recalled at the end (Notice that the formula begins by $\binom{5}{0}$ but your sum by $\binom{5}{1}$). I want to finding all combinations in an array to reach a given sum. Subarrays can contain duplicates.
