Yes, absolutely! And I think my critique was a bit unjust: You've found 
a valid, logical solution that works fine (apart from the small "inject" 
mistake). So you've done a good job.

What I was talking about is the next step: improving the programming 
style. When you've found a solution, it's always a good idea to try to 
improve it and think about alternative approaches.

For example, you could ask yourself: Do I really need to save all 
elements in an array? Or you could look for built-in Ruby methods to 
solve the task: How can I create a "sequence object"? How can I select 
all elements up to the first one that doesn't fulfill a condition? etc.

I've found this to very helpful in the learning process. Solving a 
problem is one thing. Digging deep into the language to find a better 
solution is even better.
