I believe it's the hash value (someone please correct me if I'm wrong) and I'm unsure why it's the hash that gets printed out and not what you see. To print out what you're expecting, see here: http://stackoverflow.com/questions/11399950/why-do-i-get-garbage-values-when-print-arrays-in-java#11399956

I feel like I'm pretty close but get the following results:

Test Results:
basicTests(DigitizeTests)
✘ Should work with some preset numbers: array lengths differed, expected.length=8 actual.length=5
randomTests(DigitizeTests)
Log
Testing 37 random numbers...
✘ Should work with 12: array lengths differed, expected.length=2 actual.length=5

Can anyone help explain what this means? I've tried different array lengths with no progress. Thanks!
Also, I'm new to codewars, is there anyplace to share code safely?
