Even though you also have posted the correct very close to the same time when dharanidharan posted, due to slow internet connection or whatever reasons your reply has come late. This is people say LUCK. If you take running race, even if the difference between the times of two persons are less than a second, only one is declared as winner. So don't lose your heart. Wish you better luck in subsequent contests.
So winner of the contest on January 17th is Dharanidharan.
