The other day, Tim are asking Jim and Hysramp to play his newly invented game describe as follow. Tim randomly change the time of his lovely alarm clock then ask Jim and Hysramp to tell the degree between hour finger and minute finger. Jim seems quite gifted playing it while Hysramp does not. When Hysramp fails to answer Tim, Tim smiles to Hysramp, and Hysramp smiles to you, an ace programmer.
