A4Q2 quick question on gcd

[Cong]

there's a counter for gcd for printing statistics, do we just
implement a private gcd function which takes two Rationalnumbers where
it says "//YOU MAY ADD OTHER PRIVATE MEMBERS"? or did I miss something
obvious?

[Cong]

or is it that we define a gcd function that take two ints and is used
for reducing Rationalnumbers?

I think there is no gcd between two rationalnumbers, so...

You are free to add any private members (where indicated) that you feel
are appropriate, which can include routine members.

I'm a bit confused about where and how I need to define extra functions
like gcd. Is it best practice to put it directly in the interface file
with its full definition, just put its prototype in the interface file
and define it externally in the implementation file, or just define it
in the implementation file and not at all in the interface file.
