How did you calculate that? > b) xrange long int overflow : > > for i in xrange(0, 1 << len(S)) : > ........ > OverflowError: long int too large to convert to int Why do you bit shift a len result here? Just to get a huge number? Try the same with C. You'd get an integer overflow in the first place. But this long int => int issue should not exist in a future python version any more, IIRC int and long int is scheduled to be merged somehow. (Or isn't it?)
