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!

Extracting only immediate children in a Modifed PreOrder Traversal Tree

Asked by mjeet in PHP and Databases

Tags: get

Hi,
  I am planning on using the modified preoder traversal tree for trees. To get the children of a parent one can just query "where lft > parent.left and rgt < parent.rgt" .But I need to just get the immediate children of a parent.

For ex.
                                     0 Root 13
                                          |
                                  ----------------
                                |                   |  
                            1 Child1 6       7 Child2 12
                               |                      |
             ---------------              ------------
            |                  |           |              |
     2 SubC 3     4SubC  5    8 SubC9    10 SubC 11


So the immediate children of Root would return just Child1 and Child2 (Not SubC's). it's trivial in the adjecncy tree but in this it has just boggled me.. maybe iam looking at it from a different angle.
