Is there something wrong with 4Clojure?

[ctzsm]

Hi,

Now I'm doing the problem 164 (Language of a DFA). (Please click here)

But as you know, this problem is very difficult, a solution can get a stackoverflow or timeout very easy.

After implement a solution, I'm keep getting timeout now.

However, the problem occurs when I want to know how a solution can get a timeout, so I just try a test function as follows:

(fn [m]
  (let [al (m :alphabet)
        s (str (first al))]
  (for [i (range 1000)] s)))

oh my god... this function got a timeout in this problem!

the problem has some very big test cases, if 4Clojure can't make the test function "You failed the unit tests", I don't think one can pass this problem.

And maybe a reasonable number for my test function is not just 1000 but more than 10000.

Can anyone tell me something about it?

Thanks in advance.

Yours.
