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...
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...
A node label for node filtering. If a node label is provided, vertices matching the label are the only vertices that are included, including vertices in the input list. traversalDirection(optional)–type:string;default:"outbound". The direction of edge to follow. Must be one of:"inbound",...
(randomly chosen)numeric priority. As with any binary search tree, theinorder traversalorder of the nodes is the same as the sorted order of the keys. The structure of the tree is determined by therequirementthat it be heap-ordered: that is, the priority number for any non-leaf node ...

Standard breadth-first search (BFS) is an algorithm for finding nodes from a starting node or nodes in a graph in breadth-first order.
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. ...
