Tests are apparently intended to expect Numbers in all cases, except when the result should be an empty String or an Error. This is less than ideal ( expecting inconsistent return datatypes is not a best practice ), but IMO the description does a reasonable job of specifying it.

All examples, and the note at the end, point to the value of an expression being a Number. This could have been specified explicitly, you could consider that an oversight, but I wouldn't really consider that a breaking issue. It's a reasonable default, and nowhere are Strings accepted where a Number should have been returned.

Does that answer your question?

@mjwebb I'm guessing your solution is modifying the incoming array of numbers. Looking at the randomized tests, it passes the same array (passed by reference) into the reference solution as well as into your solution UDF. I'll submit a change to duplicate the array so this doesn't happen. In the mean time, you shold be able to duplciate the incoming array yourself to avoid the issue.

input = duplicate( input );

My initial ColdFusion tests pass, but my submission attempt is failing with the followng message:

Expected [((12) 0) 7-27-8] but received [(120) 727-8196]

This looks like the expected result is wrong to me??

Approved.

Approved.

Thanks Brad , Revised and APPROVED

• Well , Thanks Brad for notifying me

• I've encountered the Same Dilemma in Consective Ducks in other languges, in which it was a must to reduce the number of iterations to run under its time limitations

• So Don't worry about it, It Still has Linear Solution and Consistent with Testing Criteria of not letting any higher Order Solution able to pass, So It's Fine ..

Please let me know if that's not the case and there's anything I can do to improve on it

• You've have done a great Work Brad , and I'm the one be grateful to your exerted Efforts, Regards .. Zizou

Thanks! Those are... hairy indeed :) I'll see what I can do to come up with something similar in CFML.

Well, have fun ;)
