If my over-use of str2num has in any way caused offense, I hereby beg leave to apologize.
My hat's off to you for such a solution. I'm baffled as to how to decode it (pun intended). I know that there has been a lot of furor over the use of regexp and other string-based functions, conversions, etc. to lower solution sizes for problems in general, but this problem is string-based, so I see no problem in solving it via arcane string methods.
Which doors are open?
Increment a number, given its digits
Getting the indices from a vector
Combined Ages 2 - Symmetric, n ≥ 3
Mersenne Primes vs. All Primes
Divisible by 2
Sphenic number sequence
