Can you solve this real interview question? Construct Binary Tree from Inorder and Postorder Traversal - Given two integer arrays inorder and postorder where inorder is the inorder traversal of a binary tree and postorder is the postorder traversal of th
Given two integer arrays, preorder and postorder where preorder is the preorder traversal of a binary tree of distinct values and postorder is the postorder traversal of the same tree, reconstruct and return the binary tree. If there exist multiple answers, you can return any of them. Example...
If the inorder list is empty, we return None as there are no elements to build the tree from. We call the helper function build_tree_helper with initial boundaries 0 (leftmost) and len(inorder) - 1 (rightmost) to build the entire tree. 4. Return Value: The function returns the root...
