Hello Codeforces!

I was solving this problem

http://mirror.codeforces.com/contest/810/problem/C

and it gives me a lot of WA, here is my code

27302116

but after that I got an AC, because i just implemented this "+Mod" in this line

-- Sum=(Sum-der)%Mod;

And finally I stay like this

-- Sum=(Sum+Mod-der)%Mod;

why does it happened?
