These day im trying to improve my dp skills and then i faced this problem. I did come up with da solution and then... It bugged :(

First thought occured in mah mind was that if i was miswrite at some line... But i havent spotted it until now :|

Maybe i did not implement it in a correct algo? Or somehow mah eyes so dumb that i cant see the error... Thanks and appreciate all of your helps!
