  3. You are given huge amount of integer data & a continuous stream of data is coming. How will you find kth largest element always.

At first i started with quick select , then was asked to think better. Then, my next approach was taking an amount of data like 10MB always & using Merge Sort to sort the large amount of data. But then i realized it could be made better by using priority queue of size k. So, i gave them this approach of taking k size priority queue & every time an element greater than the smallest element in the queue comes we replace it by new element. They were satisfied with this approach.
