A little work in the custom test tool reveals that something is wrong with your logic that handles the cases that are preceded with the '-' character. It is possibly an infinite loop or undefined behavior. I am not going to spoil the fun of debugging for you. So I'll leave it to you to find out the root cause from here.

Just don't create static arrays locally ... create them globally with MAXN size i am refering to 

bool vis[n]={false};
ll freq[n+1]={0};
set<ll> br[n+1];

just move them to the global scope and make them like this

bool vis[MAXN]={false};
ll freq[MAXN]={0};
set<ll> br[MAXN];

and get AC :)
