Runtime error in CENS20G - Help Please

There’s no reason that I can see why using map<ll,ll> m; should break things (it’s merely a weird thing to do :)) The actual problem seems to be this: int t; cin>>t; ios_base::sync_with_stdio(false); cin.tie(NULL); cout.tie(NULL); i.e. calling sync_with_stdio after reading input. From here:

There may be other reasons, too.
