I solved one problem in my second round!

However I got only -50 points in the round.

I got +225 rating change,awesome!

(I used shared document to cheat again!!!)

I am so orz.

my code:

include<bits/stdc++.h>

using namespace std; int main(){ int T; cin>>T; while(T--){ int x,y; cin>>x>>y; if(y==x+1||((x>y)&&((x-y+1)%9==0))) puts("YES"); else puts("NO"); } return 0; }
