OK, so the goal at hand is here, I have two glasses of colored water.

And the only goal at hand is to do a very simple operation

like we needed to do quite a bit last week,

which is to swap two variables just like we swap two numbers.

So if you could go ahead and get the purple liquid in here

We want to put only purple here, and only green here,

DAVID J. MALAN: OK, but you're hesitating.

FARRAH: Because you told me they couldn't touch [CHUCKLE] and--

DAVID J. MALAN: Well, you can touch the glasses.

Supposing you can't just move things around

in memory, what if I gave you a temporary variable.

DAVID J. MALAN: So how can we now get purple in there and green in there?

So purple goes into the temporary, very nice.

DAVID J. MALAN: Green goes into what was purple.

And then purple goes in-- from the temporary variable

Now, a proper round of applause if we could.
