Y'know, we've had a lot of "alphabet" challenges recently. (one two three four five.) While I love a good challenge, and those challenges were very fun, I think it's time for a change of pace. We need to exclude such challenges in the future. It's time for automation!
You're going to find some alphabets for me, and for automation (and for glory!) Alphabets are tricky and like to disguise themselves.[citation-needed] You'll need to account for the following factors:
- Alphabets can be uppercase or lowercase (but not both). So, you need to look for
abcdefghijklmnopqrstuvwxyz, but not
AbCdeFGhIJkLmNOpQRsTuvwxyZ. That is, only look for alphabets that are composed of entirely one case.
- Alphabets can shift around. they may not always start with
A, but instead may start with
U. So you'll have to look for things like
- Alphabets may not always read forwards. They can also read backwards, up, and down. E.g.,
ZYXWVUTSRQPONMLKJIHGFEDCBAis also a valid alphabet.
Here's an example of a string that has an alphabet:
This is a backwards-oriented, shifted alphabet:
This also contains an alphabet:
F G H I J K L M N O P Q R S T U V W X Y Z A B C D E
it's a down-oriented alphabet:
F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z V A=== B | C | D | E V
Your challenge is to write a program, function, etc. that, given a string, outputs/returns a truthy value if the string contains at least one alphabet, or a falsey value otherwise. This is a code-golf, so the shortest program in bytes wins.
