| вернуться в форум | hint (if you need it) Послано Aneto  11 июл 2012 22:16I had WA5.After I spent some hours i found out that i used 100000007 instead of 1000000007, so, please, be careful.
 
 PS. If n=1000000 then answer is 71348251
 
 I hope it will help someone someday.
Re: hint (if you need it) Послано Noob  11 июл 2012 23:44Just write "1000*1000*1000+7" and be happy :)Exponential notation (1e9+7) saves nerves :-) $subject
