katrinleinweber's solution

to Two Fer in the Kotlin Track

Published at Sep 03 2018 · 0 comments
Test suite

Two-fer or 2-fer is short for two for one. One for you and one for me.

"One for X, one for me."

When X is a name or "you".

If the given name is "Alice", the result should be "One for Alice, one for me." If no name is given, the result should be "One for you, one for me."


This is an exercise to introduce users to basic programming constructs, just after hello World. https://en.wikipedia.org/wiki/Two-fer
