You will design a small program to solve the 99Bottles challenge.
You need to make the code :
- easy to understand / maintain
- easy to change
- bug free
First design round, checkout the first-round branch and make the test pass.
Second design round, checkout the second-round branch and make the test pass.
- The second iteration will add a new case.
Resist the urge to read the 2nd round tests before you do the first round.
