Q1: If there is a new Android engineer, how will you suggest the best practice of async jobs in Android? (And the detail about AsyncTask, Executor, Thread interrupt, memory leak...and so on) Q2: Give an unsorted array, find the kth smallest item (Can you do it more quickly?)

That is, given an input of something like @[@1, @[@2, @[@3, @4]], @[ ], @5], each call to nextObject will display items in the expected order.
