After a few intermediate to advanced Exercises, I decided to try something that’s a little easier this month. Still, even if you’re a pro, it helps to pull back and try something basic just to see what you can do with it.

Getting to Euler’s Number
I enjoy reading about and studying mathematics. One of my favorite books is A History of π. I’ve used this book to inspire my Pi Day (March 14) programs. It’s fascinating stuff.

Tic-Tac-Toe Evaluation
This month’s Exercise may seem like a repeat of the Exercise “We Have a Winnah!” from July of 2013. It’s not.

No Nines!
Like many innocent and silly math games, No Nines is nerdy to play but fun to code. The game works like this:

By examining the dump, you can determine if file contains the proper data in the correct format, as well as do other interesting, useful, and technerd things.

I’m certain that the nerds would love debating whether the telegraph’s Morse code system was the first binary communications network. Let them do so. Still, Morse code remains a simple communications system, translating letters and numbers into dots and dashes — which you could argue are similar to ones and zeros.

The Yorn Function
When a computer program wants to know a Yes or No answer, the function I write is called yorn().

Yet, you pulled through the term without dropping a single course. You now have your grades and want to know your GPA for the semester.
