We propose an efficient parallel algorithm to number the vertices in inorder on a binary search tree by using Euler tour technique. The proposed algorithm can be implemented in O(log N) time with O(N) processors in CREW PRAM, provided that the number of nodes In the tree is N.Masahiro ...
2) Algorithm for InorderIn this traversal first traverse, the root node then traverses the left subtree of the external node and lastly traverse the right subtree of the external node.INORD( INFO, LEFT, RIGHT, ROOT) Step-1 [Push NULL onto STACK and initialize PTR;] Set TOP=1 STACK[1...
#TODO: preorder_traversal() # 中序遍历: 栈依次存入左节点所有点,直到最左侧在栈顶。 开始抛出栈顶并访问。(例如第一个抛出2)。如果有右节点。那么将右节点加入栈中,然后右节点一致左下遍历直到尾部。(这里5和7没有左节点,所以不加)但是如果抛出15。右节点加入23.再找23的左侧节点加入栈顶。就这样循环下...
Problem: Determine whether an input array is a post-order traversal sequence of a binary tree or not. If it is, return true; otherwise return false. Assume all numbers in an input array are unique. For example, if the input array is {5, 7, 6, 9, 11, 10, 8}, true should be re...

Binary trees are very useful in representing hierarchical data. In this article, we will discuss how to print all the elements in a binary tree in python. For this, we will use the preorder tree traversal algorithm. We will also implement the preorder tree traversal in python. What is the...
This sounds like a legitimate algorithm, so we can say that when doing a preorder traversal, for any node we would print the node itself, then follow the left subtree, and after that follow the right subtree. Let’s write that out in steps: 1. Print out the root's value, ...
also provided for performing insert and delete operations, and the lookup, insert, and delete operations detect if the key range of an index node, A, does not include the key k that the operation is trying to locate, and follow a handle A.hleft to the left sibling when k≦A.kmin. ...
