We've got to fly it first. CA

(Laughter)

Let's pick one of them say this one over here.

And those are Titan and Enceladus.

With a little sidestepping, we're gonna get you there.

There are no guarantees that you will retrieve The memories you're looking for.

This is as far as I've gotten on mine.

Space is truly the final frontier.

And the reason Mars takes particular attention it's not very far from us.

You feel like you're climbing a wall of wood.

They have tremendous outreach to the people who are living directly with the effects of the virus.

So, with the combination of these technologies we can reach it all, and we can see it all.

Destination host is unreachable.

Network unreachable

Thirty seconds later, the first message went onto Twitter, and this was someone saying temblor, which means earthquake.

It's already right here.

If the machine gets to the station it'll cause a chain reaction that'll vaporize the city's water supply.

So the next thing we're going to compute is for each of the nodes, we're going to consider the set of nodes that are descendants of the node or reachable from the descendants of the node by one hop of a non tree edge and of all those nodes that are reachable, we're going to look at the post order value that is the smallest, we'll call that L.

But it shouldn't be in a formula.

Host unreachable

Network unavailable

This is a little harder to see in the picture, but starting from 5's right child I can eventually get down here.

You can't get there with thought.

To reach the North Pole is not easy.

AUDlENCE Amen!

try and understand, you just might reach him.

Are we going to be there soon?

So goes to E, and then E could be many things.

Those are the okay nodes because they are numbered less than k and some of the nodes maybe including j itself are numbered higher than k, and we're not allowed to step on those.

So our base case says that if we've met our target, then we don't need any time to spread in order to reach the target because we're already there.

The is a terminal, so it always stays the same.

Well, let's go through and see what that value is.

F and G and itself that it can reach no other nodes by non tree edges and the smallest of those numbers is two.

And hope, of course, is the topic that I'm supposed to be speaking about, which I'd completely forgotten about until I arrived.

And if you search for a zero, you go to the root, you immediately go left to hit a null pointer.

But we can't get to it.

Now the purpose of the vehicle though, the purpose of the technology, is to be able to reach anywhere in the world in less than 60 minutes.

Those are the times that they should be contributing to Africa's development.

Where's the younger version of those kids going today?

Within less than 50 years, it'II be here.

Today, we're nearing 7 billion people.

We have one day before the Vikings attack Kells!

To get to Udacity.com we didn't have to go very far geographically.

So once he gets to that point of beginning to create,

chop faster! heave, men! heave!
