OJ Board

I still can't submit my programs through any methods......
Seems that the new system is still not working properly

I'm 16 years old.
I've solved 158 problems in UVA and 120 problems on other online judges.

Me too
I hope that the online judge management team can fix this problem as soon as possible!

Thanks for your reply! It seems that I have to wait....
Anyway, I will continue to solve problems and submit them after the system is OK.

I'm trying to submit my problem by email, but it fails. An email returns show me that I should use the submit-o-matic. However, when I submit the same solution by submit-o-matic, the error message `Access Denied' is shown in my judge status: 3751100 2005-07-15 09:52:52 Access Denied 0.000 Minimum 41...

I suffered this problem when I used an array 1..350 to store the information.
However, I don't know why, when I stored it in a 1..350,1..350 array with rotation, e.g.

1: rbwrbwwbr
2: bwrbwwbrr
3: wrbwwbrrb
e.t.c

then I got accepted. XD

Thanks a lot.

>>it's enough to remember two best solutions for each vertex
If I remember all the solutions of a vertex, can I speed it up to O(N)?

I've passed this problem.
A small hint: The length of all prime palindromes must be odd.
For example, there is NO prime palindromes within the range 1000~9999, 100000~999999.

I want to get some hints on this question:

I've no idea to solve this problem. Can you help me?

Thanks a lot!
