Anyway, I will continue to solve problems and submit them after the system is OK.

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

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.
