I have got the same problem. And it's very difficult to understand from Output to realize that directories should be stacked.

I agree. I specifically jumped into the discussions to deal with this.

The rules should definitely mention about that your 1. point. Spent way too much time thinking my code is not working only to realize this after coming to comments

Agree, the stacked direcetories( a, a/b, a/b/c ) should be an example, and the headers(https://) should be explained ahead of time.

You're right, man. In this kata, instead of learning programming, we learn to pass tests
