Finite State Machines, adding a lexer that follows them automatically,

You might think, Boy, is there a context expensive grammar out there? What's the opposite of free?

The brain is recording all information and driving all change in temporal context.

These grammars that we've been introducing describe something new context free languages.

It relates grammars to parsing, which is one of the concepts in this class.

And if you look at these qualities in the context of compassion, we find that the cognitive and affective components of compassion understanding people and empathizing with people inhibits, tones down, what I call the excessive self obsession that's in us, therefore creating the conditions for humility.

Units 3 and 4 were relatively abstract to some degree, intentionally so.

Number one, you don't choose the stone the stone chooses you.

It depends on the context.

This branch of the family is all about representation.

I am just gonna pause for a moment to let you think about that.

J is assigned the value 3.

At a high level, here's the problem description that we'll be tackling today.

So in lecture, we spent a lot of time learning about context free grammars and languages.

like HTML or SQL, the language of database queries.

But that's an example of an application that also uses this sort of linguistic analysis perhaps a little less related to context free grammars but still in the same vein.

'Poisonwood', 'Bible' , and the function we're trying to maximize is len the string length function.

Well, because, sentences are more interesting.

All of that is going to matter for figuring out the true interpretations of programs.

The set of languages that can be described by re write rules or grammers like this are called context free languages.

Here I've written down four claims.

Y has the value of 2.

But if right above it I've written X 0, then we'd get a different answer.

It handles LL. It handles LR. It handles LALR.

That line above it is the context.

And understand its interactions with the entire Earth.

This is called being lazy, and it's a phenomenal virtue when you're writing programs.

There are three components of compassion.

reducing your need for oxygen. No.

Actually, they're both just concise notations for specifying possibly infinite sets of strings.

And the last is the word_element, luftballons.

One in 90 among us experience graphemes, the written elements of language,

So this is one, one, so this is just the element wide comparison of all four element variable lower case three and it returns true or false depending on whether or not it's less than three.

... the misspelled word shown in context...

It turns out that interprocedural data flow analysis is the same problem as, in a theoretical sense, context free language reachability, which is the same problem as could I generate a string in a context free grammar.

All right. So, it's another one of these puzzle like questions.

They're the actual input that we're trying to match.

Sometimes this statement is true, and sometimes it's not.

A context free grammar can capture the language a N and b N, where N is the same.

That's much more important than knowing the particular syntax for any language.

The concept conjures of thoughts of our species, our planet and our civilization.

So all the examples we've seen so far, all of the elements in the list had the same type.

Here my grammar had three rules, and here my grammar is a list of three elements.

The second element is the expression the condition that determines whether or not we execute the loop body.

If i is the last element of the string, then we've got a problem.
