  • $\begingroup$ I rolled back my changes. @kglr 's comment is suggesting the same change. Is there a reason you prefer to retain your version? $\endgroup$ Commented Feb 20, 2019 at 18:21
  • $\begingroup$ My answer works. If you want to optimize my answer, you can add your suggestion as a comment or upvote kglr's comment. Thank you. @MarcoB $\endgroup$ Commented Feb 20, 2019 at 18:23
  • $\begingroup$ @briennakh It certainly works, but the usage of Length[#]& where Length would suffice is unnecessary. This site is collaboratively edited, so I made a change that, in my opinion, improved this answer for future readers. Anyway, I will leave it as it was; perhaps you might consider making a change yourself. $\endgroup$ Commented Feb 20, 2019 at 18:33
