Title: Graph Theory exercise

Hello everyone,

I wrote this short exercise in conjunction with applying for a job with Khan Academy. It's an exercise about Graph Theory, which may or may not fit in your current knowledge map. (Specifically, the exercise is about counting faces of planar graphs.) I think it can be ignored for now, but it might be useful one day :)

Cheers,
Josh
