Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
I have never used ruby before, so I apologize for any strange terminology I use.
Your issue seems to stem from this line:
return s[(n-(n/2)-1),(n-(n/2))]I believe what you THINK it is doing is incorrect. You seem to be trying to use it as a range. For example, if I wanted to get position 3 and 4, I would say
s[3,4]. That, however, is wrong. (I believe that you would just uses[3...4]for that).What that array call actually does is that it gets the first number and then the next n numbers (s[StartingIndex,NumberOfIndexesToGrab]). So it actually looks like this:
s[3,4] = position 3, 4, 5, and 6. That is why you are getting 3 letters on the word Middle instead of 2.To Fix this, you have 2 options. If you want to do it the way you intended, then you need to use the ... operator to get a range of numbers:
return s[(n-(n/2)-1)...(n-(n/2))+1]or to get it the other way, you just need to change the second part to a 2 so that you only grab 2 entries:
return s[(n-(n/2)-1),2]Both of those should give you the answer you are looking for. If you have any questions, or if I didn't explain something well enough, let me know.
