Given a tree, you are supposed to tell if it is a complete binary tree. Input Specification: Each input file contains one test case. For each case, the first line gives a positive integer N (≤) which is the total number of nodes in the tree -- and he…
题意: 输入一个正整数N(<=20),代表结点个数(0~N-1),接着输入N行每行包括每个结点的左右子结点,'-'表示无该子结点,输出是否是一颗完全二叉树,是的话输出最后一个子结点否则输出根节点. trick: 用char输入子结点没有考虑两位数的结点…
