I also had WA on test#8(now I have AC). I don't know this test, but look:
 N = 362880
Right Q is 2578899.
You see: all numbers(digits)in Q must be sorted:
2<=5<=7<=8<=8<=9<=9 - it's condition for minimal Q, but
you must surch begining from 9

May be this helps. If input is 12 output should be 26 not 34 .

It is something strange...
My program outputs 10, when input is 0, in your examples: 12 -> 26, not 34, but I have WA#8, why????? Program is correct, maybe tests are wrong???

if I using __int64 I have overflow too. In this problem must use only string for result.
Re: Test #8
Posted by mss 12 Mar 2009 00:38
I used recursive algorithm. (C++)
result and local variables in function must be __int64(long long)
In other cases you'll get an overflow
Usage of string not are obligatory

Test#8 is:

N=1 000 000 000
Q->555555555888

for examle with local or result variables of type unsigned you'll get
Q->1504774704

Sorry for my English :)

I don't know if what is exactlly the test but the answer is something like -1 or 26 ;D It works for me there after fixing that... ;)

Yep... problem in java was using int instead of long.
