Binary search tree post order traversal
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. WebOct 31, 2012 · There's a simple way to reconstruct the tree given only the post-order traversal: Take the last element in the input array. This is the root. Loop over the remaining input array looking for the point where the elements change from being smaller than the root to being bigger. Split the input array at that point.

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.
