preorder,在遍历左侧元素的时候,每次已经先取到元素了(最顶层) inorder里,遍历元素的时候,直到所有的left走完了,才取到第一个元素(最底层的) postorder里,也是遍历到最底层,但是下一步就是取兄弟节点了 2021-11-29-17-45-31.png inorder一个重要特征:它是从小到大排好序的! 2021-11-29-17-52-57.png ...
Find postorder traversal of BST from preorder traversal in C - In this problem we are given an array preOrder[] that represents the preorder traversal of the binary search tree. Our task is to Find postorder traversal of BST from preorder traversal.Let

Binary search trees allow fast lookup, addition, and removal of items. They keep their keys in sorted order so that lookup and other operations can use the principle ofbinary search: when looking for a key in a tree (or a place to insert a new key), they traverse the tree from root ...
