Generate subsets using Bitmasking

#1

The length of the string shouldn’t exceed 64, isn’t it?

#2

Yeah thats right…

#3

then why is the length taken to be 100 at the time of declaration?

#4

taking 100 won’t cost us much memory… Its general practice that people take more memory that the constraints given… so that if by chance a wrong test case is given which just exceeds the limit, they still pass.
