First T1, not under the circumstances T1:
20 to 30 minutes if not a little idea violent direct kick away.
Then T2T3 overall score and code complexity violence. Even think about positive solutions, industry codes, then Esen put off.
Then go back and think T1.
Note calm and steady. Try a simple point of view, looking for nature, hit the table, guess nature, guess simple approach.
To randomize problem, but do not waste too much time on this.
Pay attention to check whether the complexity will leave.
Details uncertain issues must be on the beat.
