Dragon Book Exercise Answers

[Georgeanna Abson]

Istarted doing exercise 2.4.5 in Dragon book second edition and found some answers in internet but they seems wrong for meFirst of all this is the exercise:Construct a syntax-directed translation scheme that translates postfix arithmetic expressions into equivalent prefix arithmetic expressions.

I tried to evaluate translation scheme which I found in internet for values 952*-, 95-2* and it seems to be incorrect. In contrast my scheme works good, but I am not sure about other edge cases which my translation scheme may hide.

For this exercise you get an initial question, then the path of sorts branches depending on your answers. This process can end after only two answers in a couple cases, but generally takes three. Regardless, there are four possible monsters: Mud Mannequin, Cruelcumber, Fright Bulb, and Platypunk.

On the other end, Mud Mannequin probably has the least utility of the bunch, because status ailments are pretty pointless that early in the game. Fright Bulb is more magic-friendly, while Platypunk is a stocky little bruiser.

Lucas plays a lot of videogames. Sometimes he enjoys one. His favorites include Dragon Quest, SaGa, and Mystery Dungeon. He's far too rattled with ADHD to care about world-building lore but will get lost for days in essays about themes and characters. Holds a journalism degree, which makes conversations about Oxford Commas awkward to say the least. Not a trophy hunter but platinumed Sifu out of sheer spite and got 100 percent in Rondo of Blood because it rules. You can find him on Twitter @HokutoNoLucas being curmudgeonly about Square Enix discourse and occasionally saying positive things about Konami.
