Bruno P. Kinoshita commented on TEXT-77:
----------------------------------------
>What is the use case for this?
It could be used for [text
compression|http://www.sciencedirect.com/science/article/pii/S0304397508008852].
However, I suspect it would have to be implemented as the [longest common
sequence|https://github.com/apache/commons-text/tree/master/src/main/java/org/apache/commons/text]
similarity that we have (i.e. for any given substring, find all its possible
palindrome values in the string).
Palindromes and longest common subsequence have use cases in bioinformatics;
though I don't intend to quickly implement anything (which I agree would be
pretty trivial).
Instead will read a few papers to confirm that it would be useful for other
components in ASF (in mind I have only
[Taverna|https://taverna.incubator.apache.org/introduction/taverna-in-use/bioinformatics]
so far) as well as external projects. Happy to close and archive the issue
later if not helpful to any other projects.

> Project: Commons Text
> Issue Type: New Feature
> Reporter: Bruno P. Kinoshita
> Priority: Minor
> Labels: easy, help-wanted, text

> 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".
