# Largest Series Product

Given a string of digits, calculate the largest product for a contiguous
substring of digits of length n.

For example, for the input `'1027839564'`, the largest product for a
series of 3 digits is 270 (9 * 5 * 6), and the largest product for a
series of 5 digits is 7560 (7 * 8 * 3 * 9 * 5).

Note that these series are only required to occupy *adjacent positions*
in the input; the digits need not be *numerically consecutive*.

For the input `'73167176531330624919225119674426574742355349194934'`,
the largest product for a series of 6 digits is 23520.

To run the code in this exercise, you will only need to have [CommandBox CLI installed](https://ortus.gitbooks.io/commandbox-documentation/content/setup/installation.html).  This binary runs CFML code from the command line.

To run the tests, `cd` into the exercise folder and run the following:

```bash 
box task run TestRunner
# Or start up a test watcher that will rerun when files change
box task run TestRunner --:watcher
```

The tests leverage a library called TestBox which supports xUnit and BDD style of testing.  All test suites will be written in the [BDD style](https://testbox.ortusbooks.com/content/primers/bdd/specs.html) which uses closures to define test specs.  You won't need to worry about installing TestBox.  The CLI test runner will take care of that for you.  You just need to be connected to the internet the first time you run it.  You can read more about it here:
