Simple Circular Words A "simple circular" word is a word whose chords do not intersect.  The chords of a word may be seen by laying out the alphabet in a circle, and then connecting the word's consecutive letters. 

Examples of Simple Circular Words

ROLE



LAKE



BALMY



Failing Example

A word fails to be simple circular if any of its chords intersect:



The Challenge

Write a program or function that takes a word and returns true if it's simple circular, false otherwise.


Code golf, fewest bytes wins.
Standard rules.
You may assume there are no repeated letters in the word.
You may assume every word has at least 2 letters
You may assume the word is all uppercase, or all lowercase, whichever you prefer.
You may output any two consistent values for true and false.


Test Cases

True

ROLE, LAKE, BALMY, AEBDC, ABZCYDXE, AZL, ZA

False

BONES, ACDB, ALBZ, EGDF

A regex solution that finds if there are four characters in the string such that the two later characters are in different sections of the circle, as defined by the first two characters.

                 # Effectively, if only one of the 3rd or 4th character is in that range
