Binary search tree post order traversal
WebAug 12, 2015 · In post oders traversal, root can always be found at last node, so it will take o (logn) time complexity. Now, in quick sort, take root as pivot and the elements less than the root will be at left side and rests will … WebNov 21, 2014 · The logic of Post order traversal without using Recursion. In Postorder traversal, the processing order is left-right-current. So we need to visit the left section first before visiting other parts. We will try to traverse down to the tree as left as possible for each node of the tree.

WebThis tutorial discusses different ways for traversing a binary tree (pre-order, post-order, in-order) with algorithms. Binary Tree Traversal. A binary tree can be traversed in three different ways, namely, pre-order, post-order and in-order. The order in which the nodes are visited differs between these techniques.
