WebJun 16, 2024 · Given a preorder traversal of a tree, say a-b-c-d-e-f, you can guess a tree as follows: use the first element as the root, partition the rest of the sequence in a number of subsequences than will correspond to descendants, left to right, repeat recursively. E.g. abcdefg a / \ bc def g a / \ b d g / \ c e f WebMar 24, 2024 · 4. Reconstructing a Tree From Its Pre-Order and In-Order. To reconstruct our tree from its pre-order and in-order sequences, we start by looking at the first element of the pre-order sequence. Since pre-order traverses a tree starting with the root, then the left node, then the right node, we know that the first element 6 is the root of our tree.
