whats the problem ? if no extra memory allowed then can't be done in better then O(nlogn)sorting time & O(1) space else it will take O(N) time & O(N) Space
sorting will change the order but using bitmap or bitarray order will be preserved Thanks Shashank CSE,BIT Mesra -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
