Charles Honton closed TEXT-77.
------------------------------
    Resolution: Won't Do

This is a great academic / interview question with little practical use.

What is the scope of requirements?  What is the expected big O performance? Which of the following palindromes will it detect?

Madam, I'm Adam
Able was I ere I saw Elba
A man, a plan, a canal - Panama!
かるいきびんなこねこなんびきいるか
上海自来水来自海上
Dábale arroz a la zorra el abad.
Adán no cede con nada.

> I had a look at [lang|https://commons.apache.org/proper/commons-lang/javadocs/api-release/index.html] and [text|https://commons.apache.org/proper/commons-text/javadocs/api-release/index.html] API's, but could not locate a class/method for [palindromes|https://en.wikipedia.org/wiki/Palindrome].
> Ideally, it would support words or sentences such as "racecar" and "step on no pets".
