Finally i got the idea behind using bitmask with Dp as rng_57 said it's just used as state.

thanks you also olimpo your link is very useful .
I understood this with the help of this TC problem  from last SRM 522 
it's really helpful.
now i want to practice if any one know problems on  DP with Bitmask  please mention it.but please try to mention  if the problem  easy or medium or hard.
thanks in advanced.
