Hi Monks!
I have the following sturcture:
{
  "tool": "A",
  "version": "1.3",
  "dependencies": [
    {
      "tool": "B",
      "version": "8.23",
      "dependencies": []
    },
    {
      "tool": "C",
      "version": "2.1",
      "dependencies": [
        {
          "tool": "D",
          "version": "1.1",
          "dependencies": []
        }
      ]
    }
  ]
}

You can think of this data structure as a tree: 
  A
 / \
 B C
   |
   D

I want to do a postorder traversal on this tree and to be able to print the tool/version. So I get: 
B/8.23
D/1.1
C/2.1
A/1.3

The problem is that I'm not sure how to to do it. I need to find each leaf and then remove it (???) in order to mark that "I was here". I'm sure that there is a better way to handle it and this is why I'm asking here. Is it possible to suggest a better way?
