For each tutorial we release there will be a relevant challenge where the winner receives 1 STEEM! 

### Challenge

Take the code from the tutorial from [here](https://github.com/amosbastian/steempy-tutorials/tree/master/part_18) and change it to be able to do the following

1. For a given account's top 10 resteemers check how many people they are actually reaching with their resteems. What I mean by this is: calculate how many people are following them that don't also follow the given account and sum this.

That's it! Good luck to everyone participating!

### Deadline
The prize money will be rewarded to the person that solves the problem first. If there is no solution within 7 days after this post has been submitted the prize pool expires.
