@nicks so many problems could be solved in O(n) but it is very difficult to find a hashing function where there is no collision... and if we sort the list, we are modifying the list... which lets assume is not allowed............. then what to do ? suppose even if we know the index at which there are duplicates for every unique number even then the solution will be O(n^2) because you cant jump directly to that index
