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 ...

An algorithm is presented for rapid traversal of octree data structures, in order to enhance the speed of ray tracing for scenes of high complexity. At each level of the octree, the algorithm generates the addresses of child voxels in th... M Agate,RL Grimsdale,PF Lister - Springer-Verlag...

(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 ...
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...
