Give the pre and post number of each vertex

Webvertex that is marked, but has no unmarked children. Then the post order of v equals 1. For the recursive case, suppose v is a vertex and the post order of each of v’s children has been computed. Then the post order of v is one more than the largest post order of any of its children. Henceforth we let post(v) denote the post order of v. WebIn a binary tree, we only have up to two neighboring choices: From the current vertex, we can go to the left subtree first or go to the right subtree first. We also have option to visit the current vertex before or after visiting one of the (or both) subtree(s). This gives rise to the classics: pre-order (visit current vertex, visit its left subtree, visit its right subtree), in …
