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!

Multi Level Sorting Algorithm in Perl

Zones: Perl Programming Language, Miscellaneous Programming, Algorithms

Tags: Perl

Given a hash : %detailModel

with keys: $model = "Alpha Name of Automobile"

Holds Values as Pipe Delimited (E.G): PICKUP 1/2T|999999|1999|DODGE|2003|99

So Thats: Make|Account|Year|Make|TaxYear|Seq

I want to sort this data by model, make, year, seq

I am lost on how I should go about this.

When I initially loaded the hash if there were multiple occurrences of the same model I just tacked on a decimal to the word (e.g. pickup 1/2.1). This actually worked and got me around that so I could use a hash as the sorting function. However if I reload a hash with a new key after sorting it once I will lose the sort from the first sort... hope that made sense.

I figure somebody will get kinda what I talking about and have at least some pseudo code that will shed some light on this.

I am a beginner with Perl so please add some comments/explanation to any code.

Thanks in Advance!
