The Contest Problem

Daniel: Hey Quan, we just received a shipment of 25 Macbook Pros from Apple Inc.

Quan: WOWIE PAZOWIE! What are we going to do with 25 Macbook Pros?

Daniel: Lets keep 3 of them for personal use and give the other 22 away to the winner of this contest.

Quan: Okay. But personally, I think the winner would rather prefer a 10 dollar GC to amazon.

Daniel: Youre probably right. In that case, well just take a sledgehammer and smash the other 22 laptops to oblivion. Anyhow, since all Macbook Pros are not created equally, lets determine which 3 Macbook Pros are the fastest. Those are the ones that well keep.

Quan: Good idea. We can go to the computer lab and run a simple test.

Daniel: Right. We can hook them up to the blinkdagger station and have each laptop process a special algorithm that I developed in MATLAB.

Quan: But we can only hook up 5 Macbook Pros at one time. And the station only ranks the 5 laptops from 1 (fastest) to 5 (slowest). It doesnt give us any other information. This could potentially take forever!

Daniel: Dont worry Quan. The optimal strategy will only take ______ iterations.

How many iterations do Quan and Daniel have to run to determine which 3 Macbooks are the fastest?
