Say hello to a not-so-simple, 4x4 word square:
This little monstrosity has two rules; to define the first rule, have you ever heard of a heteropalindrome?
Strings of letters that form words when read both forward and backward (e.g., "deliver" and "reviled") are termed heteropalindromes.
Now you have, and with that out of the way; the first rule is that the result for each row and column, must be classified as a heteropalindrome, as described above. For example:
[s, a, g, a] [p, , , ] [a, , , ] [s, , , ]
The second rule is simply that words must be contained in YAWL.
Your task is simple, complete the word square, while meeting the aforementioned constraints. The first answer meeting the aforementioned requirements will get the checkmark.
