Write a non-recursive traversal of a Binary Search Tree using constant space and O(n) run time

This is not homework, this is an interview question. The catch here is 开发者_运维知识库that the algorithm should be constant space.[详细]

Get path from every leaf node to root in a tree structure

How can I turn this tree structure [1, [2, [3, 4]], [5, [6, [7], 8]]] 1 2 3 4 5 6 7 8 .... into this \"reversed tree\" structure, which basically contains the paths from all the leaf nodes to 1 (t[详细]

Fastest way to traverse arbitary depth tree for deletion?

For my own exercises I\'m writing an XML-parser. To fill the tree I use a normal std::stack and push the current node on top after making it a child of the last top-node (should be depth-first?). So I[详细]
