How can I open a combination lock without knowing the combination?
user
I know, I know, you’re thinking that the best option is to try every possible combination.  But that’s really inefficient!  It takes forever to try every combination, and in the end, it doesn’t even help.  Plus it’s tedious.  Let’s try to think of something smarter to do!
assistant
Do you know a way to do it?
user
I know a smart way, but I don’t know if it’ll actually work in your case.

What is it?
