每个输入文件包含一个测试用例。每个案例以包含0 <N <100(树中节点数)和M(<N)(非叶节点数)的行开头。 然后接下来的M行,每个格式为::ID K ID[1] ID[2]…ID [K]其中ID是一个表示给定非叶节点的两位数,K是其子节点的个数,后面是其子节点的一...

其实一开始,我觉得很简单,既然只看叶子节点个数,那每次输入ID[0-K]时,我进行记录不就行了吗,每次输入ID都是不同的层级,最后得到的的不就是每层孩子数,所以我在写输入的时候加了一点点变量,最后输出。 View Code 最后得分13分。。。意料之中,举例思考的时候都只考虑了二叉树,编写的过程中便觉的那如果一个...
