原创 1108 Finding Average (20分)输入合法判断
The basic task is simple: given N real numbers, you are supposed to calculate their average. But what makes it complicated is that some of the input numbers might not be legal. A legal input is a real number in [−1000,1000] and is accurate up to no more th

原创 1102 Invert a Binary Tree (25分）树的遍历
题意理解给定以序号代表结点的二叉树，输出这个二叉树的反转层序遍历和反转中序遍历数据结构因为n个结点用序号0到n-1代表，所以考虑用相对于链表更加简单的静态链表来实现二叉树，即一个结构体数组。struct Node{ int left;//设置非法值为-1 int right;}BiTree[maxn];解题思路所谓反转二叉树就是原二叉树的左右镜像输入中未出现的结点便是根结点，需要设置一个数组来标记出现的结点，输入结束后遍历此数组，未被标记的结点即为根节点反转二叉树的层序.
