Nikhil, Not sure whether I understood the problem properly or not, but If we know the range of the element's why can't we do this? for (i=min_r;i<=max_r;i++) temp^-i; and then xor temp with array elements. If it is not what you are looking for then please provide some sample input and corresponding o/p.
