An alphadrome is a word in which each letter in the first half of the word "reflects" its alphabetical "opposite" in the second half of the word. Write a program or function that returns truthy if the given word is an alphadrome and falsey otherwise.
BEEB is a palindrome. Its first letter
B "reflects" its last letter
B, and its second letter
E reflects its second-to-last letter
BEVY is an alphadrome. Its first letter
B is the second letter of the alphabet, and it reflects the word's last letter
Y, which is the second-to-last letter of the alphabet. Likewise, its second letter
E is the 5th letter of the alphabet, and it reflects
V, the 5th-from-the-end letter of the alphabet.
Like palindromes, an alphadrome can have an odd number of letters, too.
WORLD is an alphadrome.
W is the 4th-from-the-end letter of the alphabet and
D is the 4th letter;
O is the 12th-from-the-end letter of the alphabet and
L is the 12th letter. The center
R reflects itself.
Any single-letter word is an alphadrome.
Input words will include only the characters
A-Z, whichever is convenient.
Output will be a truthy or falsey value.
