Answer 1

Okay, done! Thanks for the challenge.

Edit: seeing from your rather demanding PM you didn’t get my attempt for discourse and activiation of your learning.

Let me be a bit more blunt:
This is not a place where you simply blurt your homework assignment and expect someone to solve it. At the very, very, very least you need to ask a (polite) question.
But the correct way would be to
- try it yourself first
- run into a problem
- post your question
- post your work along with it

Good luck.
