Hi,
Using the above solution, you can also try the programs to find out the palindromes. For example,
print $_ if ( $_ =~ /([[:alpha:]])([[:alpha:]])([[:alpha:]])([[:alpha:]])\3\2\1/i );
This above code matches of the palindrome of length 6.
In the same way you can apply your logic to find out the palindromes.
Hope this will enhance your view in regular expressions.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
