For various reasons there have been no articles in recent weeks; now we are restarting on a regular basis!
A the first topic for this new season, here is a little quiz. I have a function:
- For 0 it yields 0.
- For 1 it yields 1.
- For 2 it yields 4.
- For 3 it yields 9.
- For 4 it yields 16.
The question: what is the value for 5?
Answer next Wednesday (at least it will be Wednesday in some time zone).
