Hi,
Here is my substring approach.
use strict;
use warnings;
my $str = 'TTCTTCT';
my $tar = 'ATGTTCT';
my $i =0;
while (length($str)) {
if (substr($str,0,1) eq '[') {
my $index = index $str,']';
my $m = substr($str,0,$index+1);
print "Mismatch at index $i\n" unless (substr($tar,$i,1)=~/$m/)
+;
substr($str,0,$index+1)="";
}
else {
print "Mismatch at index $i\n" unless (substr($str,0,1) eq subs
+tr($tar,$i,1));
substr($str,0,1)="";
}
$i++;
}
Regards, Murugesan Kandasamy use perl for(;;);

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
