Even though many people undeestimate this, it is very important to get to phase where you can code what you know (well, it might sound stupid, but many times one know a solution one hour before end of contest, yet he ends coding 10 minutes before end when he starts his 20 minute debugging phase [and both could be significantly reduced]). . 2) Editorial.
