Higher order functions exercise doesnt have a solution

Hi, I am in the topic of Higher Order Functions. Under Functions as Parameters(chapter 3), i am unable to get the solution and move ahead with the course. Please get the solution button back.

TBH, we have no real idea of where you are stuck. Please post a link to the exercise page (copy location bar URL and paste it in a reply).

The solution button will show itself after multiple false runs i.e. press the run button a couple of times and see :stuck_out_tongue: .

But best would be to show your progress and see why it is flagged as false. Lets find out the errors in your code.
