Sep 9, 2016 at 8:03 WebContinuing on the negative results, you can't fully rebuild a binary tree from its pre-order and post-order sequentializations alone. [1,2] preorder, [2,1] post-order has to have 1 at the root, but 2 can be either the left child or the right child. If you don't care about this ambiguity, you can reconstruct the tree with the following algorithm: tso 249
