The correctness property is another language.

Does a program contain an assertion violation? Does a device driver respect certain protocols when interacting with the kernel? The behaviour of a program is a set of executions in other words, a language.

In essence, you want to substitute a sequence in a language.

You want to spot duplicate occurrences of a phrase in a document and delete the second occurrence.

Here are some practical, fairly complicated, practical problems that are approached via language theory. Formal languages play a role in computer science akin to the fundamental and game-changing viewpoint brought by algebra and topology to classical mathematics. The language theory perspective distills seemingly complicated questions about sophisticated, opaque objects into simple statements about words and trees. Languages are not dry, formalist hand-me-downs from computing prehistory. Languages and automata are elegant and robust concepts that you will find in every area of computer science. The only thing they can do in this regard is to help you think - think of automata theory as one of those courses.Ĭan you hear that noise? It is the sound of a thousand brilliant theorems, applications and tools laughing in automata-theoretic heaven. On a related note, it is the job of the university not to prepare you for the next 5 years of your life, but to prepare you for the next 50.

If you're a CS major, at some point, you need to sit back and think about the philosophical foundations of computing, and not just about how cool the next version of the Android API is. (And it won the inventor a Turing award - google BNF). This theory has made a once impossible task into something that can be completed over a weekend.

If you've ever tried this task before and got stuck, you'll appreciate how much a little theory (aka context free grammars) can help you. If you're a CS major, you'll definitely be writing a compiler/interpreter for a (at least a small) language. You'll be surprised how much coding you can avoid by principled use of regular expressions - in "practical projects", like an email server. A customized map also fills in as students earn more states.Ever used a tool like grep/awk/sed? Regular expressions form the heart of these tools. Students can study up on state facts and flags through the flash cards, and they can study interactive 3D state maps that include elevation, cities, and 3D modeled landmarks. The app also includes reference material for further learning. map to place states Connect 2, where students connect two states as they would be connected on a map and Capital Tap, where students are quizzed on state capitals and then must tap each capital's location on the state's shape. As they earn states, they unlock three other games: Map It!, where students tap locations on a U.S. As students advance, the goal line gets higher. If students get at least 60% of the questions correct in that round, they receive a random state for their map. Once the stack height reaches the goal line, that round is over. If the question is answered correctly, the student receives the answer state to pile onto their stack. The main game mode within the app is called Stack the States, where students answer trivia questions about state capitals, borders, flags, landmarks, and more. scenes, which serve as backgrounds, such as the White House and the Golden Gate Bridge. states, and, of course, the signature cartoony characters. Like the original game, Stack the States 2 features flash cards for each state, six player profiles (plus there's a guest player option), a map of earned U.S. This newer version adds more question types, two new games, an optional voice mode that reads questions and options to players, an interactive U.S. It's a more recent version of the original Stack the States app, famous for its cartoon presentation and essential mechanic of stacking states on top of each other to reach a goal. Stack the States 2 is a geography app focused on U.S.
