- In general, cin cout streams are slow in programing contests.
- To get faster IO use the C methods printf and scanf.
- Or you may put this statement before any cin or cout statement.
ios::sync_with_stdio (false);
• This statement turns off the synchronization between the C++ IO and C IO, so once you use it you can’t use printf and scanf.
