Requirements

So this is option D.

So this is option B.

Additional requirements

And finally the len operator that takes a list as its input and produces an output number that is the length of the list.

We're here because that New York Times reporter had the list of names of everybody who was in Guatemala.

I'm going to show you about leverage.

So with option three we have a list where each element of the list is itself a list.

Remember that we decided in the previous question that the way to represent index is as a list where each element of the list is itself a list and each of the element list is a keyword followed by a list of the URLs where that keyword appears.

Or, how much can I expand my balance sheet?

The first is an index, and that's the data structure we've been working with.

We are trying to get back to parsing HTML. We want to understand how to parse Web pages and turn them into abstract syntax trees.

Well Mr. Phillips phoned my office several times yesterday.

Oh, then it's not official.

It also can be a recursive definition.

looks random, then that'll in fact give you to a large degree, a lot of the collision resistance properties because just the fact that you can't predict the output amp amp the fact that it hides all this information implies it's gonna be hard to find two inputs that are distinct that map to the same output

And the element lists are lists where the first element in the list is a URL.

Now, recall that the output of a lexical analyzer is a list of tokens.

What I want you to program now is a way to assign importance weights to each of the particles in here.

We have a list where each element of the list is a list.

Then actually that's it.

The second option would be we would have a list containing as its elements lists.

Sorry, Bob. Duty calls.

So to go through an example, the black list has 2 elements.

In fact, you could even...if you..after..after you did this, you could even say..that..a

We learned about the len operator.

It looks like there are many more elements here, but len is only counting the outer elements.

It's a matter of the utmost importance.

So here's the code that we need to finish.

It's your wife. She says it's important.

It sounded urgent.

The third option, we could have a list where each element of the list is a list where the first element is the URL, and the second element is a list of all the keywords that are found on that page.

It's a list where each element of the list is a list containing a keyword and a list as its second element, and that list is a list of URLs where that keyword appears.

Each item in the list begins with an LI tag standing for list item.

So 1, 2, 3, 4, 5 should give us 1, 4, 9, 16, 25, and down here in the output it does.

a z , and the haystack string a quick brown .

And you can see the result.

Remove current element from this list

That actually doesn't work out.

If it's not, we have to add it.

Oh,we're gonna need a list.

The answer is 3, here's why the first statement creates the list with the elements 1, 2, and P refers to that list.

We'll have a list first, then a dot followed by append, and what we pass in is the element we want to append to the list.

So what we could is we could split the string into individual substrings according to the input structure and have delta debugging work on that list of elements instead.

Unfortunately, they have a slight downside, which is that thus far we've had to write out the starter list, and that's almost as much work as just writing down what we need.
