How to construct BST given post-order traversal - Stack Overflow

WebPost-order traversal can generate a postfix representation ( Reverse Polish notation) of a binary tree. Traversing the depicted arithmetic expression in post-order yields " A B C − * D E + +"; the latter can easily be transformed into machine code to evaluate the expression by a stack machine. Postorder traversal is also used to delete the tree. Web下载pdf. 分享. 目录搜索 northgate hs pa

The algorithm approach can be stated as: We first recursively visit the left child and go on left till we find a node pointing to NULL. Then we return to its parent. Then we recursively visit the right child.
