Suppose we have a set of candidate numbers (all elements are unique) and a target number. A great and classic challenge, 3-Sum and extremely popular for interviews. Writing code in comment? The first stage of Combination Sum is similar to coin combination problem. Since the problem is to get all the possible results, not the best or the number of result, thus we don’t need to consider DP(dynamic programming), recursion is needed to handle it. It can be solved with variying level of efficiency and beauty. R C = R7 + R B = 9 + 3 = 12 Ω. In the 6 numbers formed, we have each one of the digits (1, 3, 4) two times at the first place, second place and third place.

In another example, the root sum of 757 is 1. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set. Its a simple problem on the face of it, but there are a couple things that make it tricky. Combination Sum: 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.
