输入 二叉树的先序遍历序列,用#代表空树或空子树. 输出 共五行 前三行依次输出先序.中序和后序遍历序列, 第四行输出二叉树的高度, 第五行依次输出二叉树总结点数目.叶子结点数目.度为1的结点数目. 样例输入 A B # D # # C E # # F # # 样例输出 PreOrder: A B D C E FInOrder: B D A E C FPostOrder: D B E F C A36 3 1 题目很简单,基本的二叉树操作.需要注意的是输入结点之间有空格,而且输出结点时也有空格,行
Description It’s an interesting experience to move from ICPC to work, end my college life and start a brand new journey in company. As is known to all, every stuff in a company has a title, everyone except the boss has a direct leader, and all the re
哈夫曼树 哈夫曼树也叫最优二叉树(哈夫曼树) 问题:什么是哈夫曼树? 例:将学生的百分制成绩转换为五分制成绩:≥90 分: A,80-89分: B,70-79分: C,60-69分: D,<60分: E. if (a < 60){ b = 'E'; } else if (a < 70) { b = ‘D’; } else if (a<80) { b = ‘C’; } else if (a<90){ b = ‘B’; } else { b = ‘A’; } 判别树:用于描述分类
