/**

* Fruit exercise.

* The purpose of this exercise is to practice reading code and recognizing

* the traversal patterns we have learned so far. The following methods

* are hard to read, because instead of using meaningul names for the variables

* and methods, they use the names of fruit.

*

* For each method, write one sentence that describes what the method does, without

* getting into the details of how it works.

*

* For each variable, identify the role it plays.
