Hi Monks,

Yesterday, I asked about counting and recording unique elements in a list of lots of doubles. I got a lot of help, and solved problem just fine.

Today, I had a different set of data I needed to do the same thing for, so I used the same exact code. Works as far as counting uniqueness, but the output is messed up

foreach $batch_dates (@dates) {
        
        
        if ($count{$batch_dates}) {

            $count{$batch_dates}++;
            #print $count{$batch_dates} . "\n";
        } else {

                $count{$batch_dates} = 1;
        } # end if
    } # end foreach

    foreach $key(keys(%count)) {
                    
        print $key . " = " . $count{$key} . "\n";
    } # end foreach
}

Above is the code. In the out put, it first lists the correct info, key(unique id) and value(number of times seen), but then it adds in a line, printing the first key of the list, and then putting the total number of values altogether as the value.

An example

user id1 = 1
user id2 = 1
user id1 = 2

That last line is my problem. I don't understand why the count isn't working...?

• 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).
