How can I check if the integer value 1 is in the array
$substr = " 1 ";
foreach $key ( @newarray ){
if (index($key, $substr) != -1) {print "\nExist";}
}
What is wrong ?
@newarray[n]="5 10 14 16 17 20 25 26 38 1 42
+ 47 54";
Don't find because substring contains whitespace

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).
