"WebMay 14, 2013 · 1. Found the solution to my problem, the ^ is a bitflip. Thus if you have a bitmask and use the xor operator on the mask, you flip the bit on that place. E.g. 1010 ^ (1<<1) results in 1000. Same goes for 1000 ^ (1<<1) = 1010. The substraction also works, but with the xor operator you know for certain that you only touch the bit at that place ...

Dynamic Programming is a technique of doing an optimization over recursion. We store the answer for the overlapping subproblems and use that result if we need the answer for the same problem in the future. Hence, we save the time of re-computing the answer for the same problem.
