Sphinx,
What's the order of adding the characters? I'm guessing it's BFS because I got a "Too slow" response with it.
I think 3s is too little for this one. I had to open about 50 links in total so I needed like 50s to solve it.
Hi quangntenemy,
I changed the time to 6 seconds and added a note to the solution.
No luck here. 6s is still too hard.
You should update the explanation to include sublinks too. That's the key part.
Thanks for the feedback, quang. I'm checking out the challenge now...
