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. Web23 Feb 2024 · A Computer Science portal for geeks.

Web二叉树后序遍历的非递归算法：结点要入两次栈，出两次栈；为了区别同一个结点的两次出栈，设置标志flag，当结点进、出栈时，其标志flag也同时进、出栈。 WebIn an N-ary tree, postorder means traverse the subtree rooted at its children first and then visit the root node itself. For instance, the postorder of the 3-ary tree above is: B->E->F->C->G->D->A. 3. Level-order Traversal. Level-order traversal in an N-ary tree is the same with a binary tree. Typically, when we do breadth-first search in a ...
