I was so upset that I wa on #7 more than 10. I want to practice my suffix array,so I used it and used RMQ,But I wa on #7.
I very want to know what is #7.
Can the admin give the simple to me? thanks a lot

the suffix array algorithm is right cause I got AC ever using this Template~~

I got ac now cause I use a character '$' to end my suffix array . I think is ok but got wa on 7..why?
Latin alphabet letters
is not abcdefg.....ABCDGEF...?

no no no . cause my book[] is smaller.
book[500 + 20] is not enough?

I see .  the length of string is 2000
