5082：Love

There is a Love country with many couples of Darby and Joan in it. In order to commemorate their love, they will do some thing special when giving name to their offspring.
When a couple want to give name to their offspring, they will firstly get their first names, and list the one of the male before the one of the female. Then insert the string “small” between their first names. Thus a new name is generated. For example, the first name of male is Green, while the first name of the female is Blue, then the name of their offspring is Green small Blue.
