You just measured its surface area, that is the input.

Cmon I'm sure a bit more challenging problems would'nt harm the a players brain...

I would have preferred something a bit more challenging, like asking for the volume, given the surface area, rather than just the radius. Then, the two-step solution (solve for r from area, and volume from r) could be consolidated into one line (by raising the area amount to the 1.5 power and scaling the constants appropriately).

I don't know why the lead solution is like this with the regular expression. And i estime the time with tic and toc. It is not the best. What is the size here? can anybody tell me, thx.

This user (mohamed elbesealy) appears to have gamed the system, with fraudulent "likes" of this unremarkable solution submitted by 'sock-puppet' accounts. —DIV

Why is the size 2 for this solution?

This funciton fails the assertions when I run it, and it becomes size 14. I am confounded.

I am a bit bewildered about the size too. According MathWorks, it ought to be higher due to the inspection algorithm (see <>).
