That's nice! Btw I dont understand how to get less then 13.

Grzegorz Popek on 15 May 2015

Honestly, I solved it only because it kept reappearing on my list.

Carl Witthoft on 16 Dec 2015

In the spirit of troublemaking: I think the solution should accept text input, e.g. "forty-two"

Xianglong Wang on 10 Nov 2016

Is it necessary to know about "The hitchhiker's guide to the galaxy" to solve this problem or it has a different logic behind the solution?

If it doesn't have a different logic, I have to say it was a boring problem.

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