A unique binary tree can be determined by a given pair of postorder and inorder traversal sequences, or preorder and inorder ...PAT 1119 Pre- and Post-order Traversals 根据树的先序遍历和后序遍历得到中序遍历,如果树是唯一输出Yes,否则输出No。然后输出中序遍历(如果不唯一,随便输出那一棵)。
PAT1119 Pre- and Post-order Traversals(先序后序求中序) 题意: 给出先序和后序,要求如果能形成唯一的树就输出yes和中序,如果不能就输出no和任意一个中序 思路: 这题就是递归建树,根据后序中倒数第二个数到先序中寻找对应的位置,如果后序的倒数第二个数和先序的第二个数相同就说明不唯一,此时选择...
Post-order traversal is useful in some types of tree operations: Tree deletion. In order to free up allocated memory of all nodes in a tree, the nodes must be deleted in the order where the current node can only be deleted when both of its left and right subtrees are deleted. ...
Suppose that all the keys in a binary tree are 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 giv...
My DAG evaluation is similar to the examples except that: 1) The graph topology is not known a priori and can change with each evaluation, 2) post-order traversal is required since the results of evaluating a node depends on the results of its predecessor nodes, and 3) cont...
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 ...
