WebOct 31, 2012 · You don't really need the inorder traversal. 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.WebPost-order = outputting the values of a binary tree in the order of the left subtree, then the right subtree, the the current node. In a binary search tree, the values of all nodes in the left subtree are less than the value of the current node; and alike for the right subtree.
