supposing that coin values are unique:
DB<106> %coins = ( "Quarter" , 25,
"Dime" , 10,
"Nickel", 5 );
=> ("Quarter", 25, "Dime", 10, "Nickel", 5)
DB<107> %cents= reverse %coins
=> (25, "Quarter", 10, "Dime", 5, "Nickel")
DB<108> for $cent (sort {$a<=>$b} keys %cents) {
print "$cents{$cent},$cent\n"
}
Nickel,5
Dime,10
Quarter,25

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).
