вернуться в форумWhy we should use GCD in this problem? Послано BYF 29 окт 2004 19:30 I've got AC, but I don't know the reason exactly.
I just guessed it, and got AC. Re: Why we should use GCD in this problem? Послано BYF 30 окт 2004 13:55 How about this case?
5
2 1 3 4 5
I think k could be 2
2 5 3 4 1
1 5 3 4 2
1 2 3 4 5
But my program output 0
Do I misunderstand this problem or something else? |
