Hello,

After 2 months working with ruby i still bump to some of those:

what would be the simplest way (couldn't find a rand method) to
achieve a subject's task?

thanks!

If you mean that you want to shuffle the array, then:

array.sort_by{rand}

This comes up often enough that it'd almost be worth adding an Array#shuffle (and/or #shuffle!) method to core...
