The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Sorting IP addresses in Perl

Asked by sda100 in Perl Programming Language, Programming Languages, Miscellaneous Programming

Tags:

I have a hash which uses IP addresses for the keys.  I would like to cycle through the hash in IP address order, and I don't need to store the result of the sort.  Currently my code looks like:

     foreach my $item ( keys ( %ip_add_list )) {}

which obviously doesn't work (eg. 192.168.0.25 comes before 192.168.0.3).

I was reading about the pack() function in Perl, but I don't know if/how I can incorporate it into my 'foreach' statement above, or even if there is a better way of doing it, considering I don't need to store the result of the sort, just use it to cycle through the hash in IP address order.

Thanks,
Steve :)Start Free Trial
