#Did you know you can use reverse\_each?

of course, there is even _each_ 🙂

but i am suggesting this:

x=[0,1,2,3,4,5] =\>[1,2,3,4,5]  
x[-1…-6] =\>[5,4,3,2,1]  
x[-3…-4] =\>[3,2]

right now, the above return empty [].

kind regards -botp

# 

#x = (0…5).to\_a  
#x.reverse\_each do |i|

# print i

#end
