(1)已知一棵完全二叉树存放于一个一维数组T[n]中，T[n]中存放的是各结点的值。试设计一个算法，从T[0]开始顺序读出各结点的值，建立该二叉树的二叉链表表示。

(2)二叉树的双序遍历(Double-order traversal)是指：对于二叉树的每一个结点来说，先访问这个结点，再按双序遍历它的左子树，然后再一次访问这个结点，接下来按双序遍历它的右子树。试写出执行这种双序遍历的算法。

-(1) known to a complete binary tree stored in a one-dimensional array T [n] in, T [n] is stored in the value of each node. Try to design an algorithm, from T [0] started in order to read out the value of each node to build the binary tree binary list said. (2) two-order binary tree traversal (Double-order traversal) is: For each binary tree node, the first visit to this node, and then double-traversing its left subtree, and then visit this node, followed by two-order traversal of its right subtree. Write down the implementation of this two-order traversal algorithm.
