LeetCode - Combination Sum | Darren's Blog
Given a set of candidate numbers C and a target number T, find all unique combinations in C where the candidate numbers sums to T. The same repeated number may be chosen from C unlimited number of times.
Note:
All numbers (including target) will be positive integers.
Elements in a combination (a1,a2,…,ak)(a_1, a_2, \ldots, a_k) must be in non-descending order. (i.e., a1≤a2≤⋯≤aka_1\leq a_2\leq \cdots \leq a_k ).
The solution set must not contain duplicate combinations.
For example, given candidate set 2,3,6,7 and target 7, a solution set is: { [7], [2, 2, 3] }
