For example, I want to do something, but I don't know how to do it even I had tried.
A real example, I'm using an open-source library, and I want to add some of my own functions:
I may want to add a until() and trimLeft(..) and trimRight(...), that I can write it as:
But I don't find a way to do it.
Here I'm using "find a way", but I don't know if it's good. Or "find a solution"? Or "find a method"? Or some other words?
In other case, e.g. I don't know how to open a box, is there any other way(right?) to express "I don't know how to do it"?
There may be a lot of mistakes in this question, I'll be very appreciate if you can point them out.
