We've recently switched to an examination system to evaluate ability. That is, you must now get a passing mark from three group proctors, of which I am one, to gain entry.

Some of you may be asking why the [ Content Deleted ] I posted this here.
It's to discourage the legions of... people... that insist on applying without actually knowing the language...

So then, if you'd like to try, here's your first challenge:
====================================================================
Please build a parser that transforms infix notation to postfix notation. Send me a model upon its completion.

Example input: 2 + 3 * 5
Example output: 2 3 5 * +

Please note: Code quality is a factor upon which you will be evaluated.
(This is part one of two.)

Please use Google as your calculator for all infix expressions and (bitly 13qM6Gi) for all postfix expressions.
====================================================================

NOTE: Proctors have the right to pass you even if you've failed other proctors. (This is due to that fact that you need three passing marks.)

For the problem's sake, should the precedence of the operators be the same as Lua's precedence?

@blocco

PEMDAS precedence is assumed. (Fairly Lua should be fine.)

It would be stated in the problem if that was the case.

But it can have multiple forms :o

`2 3 5 * +` <==> `3 5 * 2 +`

Yep, but both are still valid... As long as the result is 99.9999999% accurate, I'll accept it.

Of course bluetaslem messes me over with 2 challenges probably both harder than this.

I finished BlueTaslem's tasks, but then could not finish my application because Colorful gave me a Google CodeJam question. :/

Not that the question is necessarily difficult, but what the hell sort of question is that?

This is a game. Being able to write code to convert from two different formats of notation of mathematics is not even fractionally relevant. You should be evaluating their practical ability to write code useful to a Roblox scenario.

If your group is simply about useless Lua questions, and not of it's relevance to Roblox then it should be clarified in the title or description of the group.

Don't like the challenge. Why would someone search in google and learn about infix\postfix notation just to get inside a group that has nothing related to that.

I think it's a perfectly legitimate question. A lack of knowledge of (RBX.)Lua will result in inefficiency. Since inefficiency is judged, it tests an advanced area of Lua well.

Lol, I already have some experience with reverse polish notation and it does have some practical uses. Cant think of any right now for lua, but it is for one a nice test.

Don't complain. I have to make something that analyzes English text and detects sarcasm/answers questions.

"I have to make something that analyzes English text and detects sarcasm/answers questions."

So, you have to make something that searches for winking smileys or other blatant display of humour, then.

Though at face value this is purely mathematical, it doesn't require large amounts of (mathematical) knowledge to complete. It tests your knowledge of parsing, ability to construct algorithms and your proficiency in the language itself.

Even if you know about other algorithms made for this purpose, you'd still have to adapt them. Also, you have to worry about parenthesis, operator precedence, and a stack based output.


@trappingnoobs
Scripting occurs in all kinds of places, and the ROBLOX APIs could be easily looked up. It's not necessary to test people on game creation, there are too many variables.
