If I understand the exercise correctly, you would have to come up with formulas for how to calculate the label of the left and right child during each method of traversal, given the label of the current node and the depth. For example, during pre-order traversal, the ...
问题描述: Given inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 啰嗦一句,可能学过数据结构的人看到题目就知道啥意思了,给的问题介绍和描述几乎没啥意思。 示例: 题目本身好像没...leet...
For each test case, first printf in a lineYesif the tree is unique, orNoif not. Then print in the next line the inorder traversal sequence of the corresponding binary tree. If the solution is not unique, any answer would do. It is guaranteed that at least one solution exists. All th...
distinct positive integers. A unique binary tree can be determined by a given pair of postorder and inorder traversal sequences, or preorder and inorder traversal sequences. However, if only the postorder and preorder traversal sequences are given, the corresponding tree may no longer be ...
