Hi,

Which data structure can perform insertion, deletion and searching operation in O(1) time in the worst case.

We may assume the set of elements are integers drawn from a finite set 1,2,...,n, and initialization can take O(n) time.

I can only think of implementing a hash table.

Implementing it with Trees will not give O(1) time complexity for any of the operation. Or is it possible??

Kindly share your views on this, or any other data structure apart from these..

Thanks..
