bThe program first reads integer memberCount from input, representing the number of pairs of inputs to be read. Each pair has a string and a character, representing the member's name and group, respectively. One Member object is created for each pair and added to ArrayList memberList. If a Member object's group is equal to $\text{'}$B$\text{'},$ call the Member object's print$()$ method.

Ex: If the input is:

$4$

Mel B Ben B Huy A Ina A

then the output is:

Member: Mel, Group: B

Member: Ben, Group: B
