Up for a Challenge?
Greetings from beautiful Yellowstone National Park!
It seems that even when I'm on vacation, my mind is in Excel mode. (Don't you feel sorry for my wife? 😂)
Here's what I mean. Some weeks ago, Yellowstone experienced some devastating flooding that wiped out roads and bridges.
As a result of the flooding, access to the park was restricted to reduce the number of visitors on any given day. The system they put in place is based on visitor license plates.
Plates that end in odd numbers can enter on odd dates and plates that end in even numbers can enter on even dates. Simple enough.
What if your personalized plate doesn't end in a number? Then entry is determined by the last numerical digit found in your plate, wherever that may land.
What if you don't have any digits on your plate at all? Then you get to enter on an odd date. Here are the official park rules for the Alternating License Plate System:
Seeing these rules immediately had me thinking of building a formula in a spreadsheet.
Can you write a formula that assesses a license plate combination and returns the word EVEN or ODD based on the rules above?
To solve the challenge, just download the Excel file up above and start writing your formula!

We also found bison out on the road checking plate numbers. They use horns instead of formulas to regulate unwelcome guests… 😬
