### 10202 -- Pairsumonious Numbers

hi all, I have a question. Could this problem solve with DP? I have tried to solve this with DFS, finding out all possibility. but it seems that my method waste a lot of time. I ponder if a more efficient way exists, just like DP. Anyone have an idea about solve Q10202 with DP? :) ---- DJWS, a newbi...
