In Codeforces Round 215 (Div. 1) 19790402 I got WA on test 79, However, I thought I got the correct answer when I used Custom Invocation.
What the problem is???
I passed this problem by replace %ld with %d, but I do want to know Why I get different answers between custom invocation and problem test?
By the way, I'm glad to know how to cause this WA, since I thought there is no different between %ld and %d in GNU G++11 5.10 :)

You should contact the admins for re-checking of your solution(there must be some problem with checker at that time since it does not show even judge output). It's correct. see the following submission — just an additional comment(to make the code run again instead of fetching stored result corresponding to above solution) — http://mirror.codeforces.com/contest/706/submission/19819586
Well,thanks you a lot. I sent message to MikeMirzayanov 8 days ago,but it is unread.Do you know other admins or know their emails?
