Albert and Bernard just became friends with Cheryl,
and they want to know when her birthday is.
Cheryl gives them a list of 10 possible dates:
--------------------------------------------------------
May 15, May 16, May 19, June 17, June 18, July 14,
July 16, August 14, August 15, August 17
--------------------------------------------------------
Cheryl then tells Albert and Bernard separately the month
and the day of her birthday respectively.
Albert: I don't know when Cheryl's birthday is,
but I know that Bernard does not know too.
Bernard: At first I don't know when Cheryl's birthday is,
but I know now.
Albert: Then I also know when Cheryl's birthday is.
So when is Cheryl's birthday?
