I don't think there is any known formula for this sequence. You have to either do brute force or cheat and look on Mathworld or the EIS. :)
Could anyone please tell me what the input format is? Is there just one number? Are there many numbers? What are these numbers separated by?
Also, could anyone say what the answer to the input 10 is? I think it should be 9189, but I'm getting WA.
Thanks.

If only I had as much free time as I did in college...

I solve 10918 to see the page as follow.WeiMing Chen wrote:I think it a math problem.
And if you want to solve it, you might use DP
Or there are some strange solutions can solve it, like 10918.
I also haven't found out how to solve it.

Is there an efficient way to brute force this?
