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!

Array hell: need to store 2 values for each entry in an array, but a lot of these are duplicates

Asked by Letterpart in Perl Programming Language

Tags: perl, array, value

Hi,

I am new to Perl and having trouble here.

I am using a regexp to extract $1 and $2 from a line in a file:

I need to then add these two values to an array so that each 'entry' has two values.

ie:

Element 0
value $1
value $2

Element 1
value $1
value $2

Element 2
value $1
value $2

I tried a hash array which was working well until I realised that it doesn't allow duplicates.

A single array doesn't allow me to store both $1 and $2 for each entry.

In Actionscript (Flash) I would just create an Associate Array and store each data pair under each entry, and this would allow me to store duplicates. But so far I have not been able to work out how to do this in Perl.

Could someone please point me in the right direction.

many thanks,
