PROBLEM 2
Shreyas wanted to enter an exclusive club but didn't know the password that was required. He waited by the door and listened. Tushar knocked on the door and the doorman said, " Twelve." The member replied," Six and was let in. Rajat came to the door and said," Six." The member replied,"Three" and was let in. Shreyas thought that he had heard enough and walked up to the door. The doorman said," Ten" and he replied,"Five". But he was not let in. What should have he said?
