I'm not sure how this impacts our customers by georgeha (4.00 / 3) #1 Thu May 11, 2006 at 06:58:50 AM EST
so I can't assign the proper priority to have a developer look into this.

Although, for free, if you're having to walk a tree breadth first I'd examine your data model before writing code.

If matter is finite, all creation necessarily begins with destruction. Consequently, there is no choice but to destroy because material beings must create to exist.

There is no more degenerate kind of state than that in which the richest are supposed to be the best.

breadth first?!?! by TPD (4.00 / 3) #6 Thu May 11, 2006 at 07:28:57 AM EST
But surely it's closer to tea time!

Your problem is that by ObviousTroll (4.00 / 2) #7 Thu May 11, 2006 at 07:51:34 AM EST
All your functions are missing the "operation" part of the traversal.

Nobody traverses a tree without doing something at each node they visit.

Here's a hint:

    #Hellllllooooooo Node!

    #actual work goes here

    # depth first
    list_of_children = node->children

    for child in list_of_children {


A breadth first version of this isn't much more subtle, but it requires handling the "visit" part differently and at a different time.

I don't think your f4 is right by jacob (4.00 / 1) #8 Thu May 11, 2006 at 08:08:37 AM EST
Though you didn't explain exactly how you're representing trees. But I think it will definitely fail for, e.g., a balanced binary tree with height 3.
