Hello,
That code will work sice the list is only one. I want to count the occurence of the combination of
the lists. and also to know how to map them.
i have 3 lists
@list1 ={sunny,windy}
@list2 = {t,f,b}
@list3 = {a,b}
and i have records
sunny t a
sunny t b
sunny f a
sunny f a
sunny b b
windy f a
windy f b
and so on , so i want to know te occurence of all combinations of these records.
then i want to count the occurence of sunny,t,a and sunny,t,b and sunny,f,a and sunny,f,b, windy,t,a,
.....
so the hash should have multiple keys i.e from list1,list2,list3.
and i could craete this as i have described in my question. but i dont know how to retrive.
i.e i have an entry "sunny,f,b " how can i know its frequency.
Please kindly let me know.
Thanks

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).
