数据结构中一直对二叉树不是很了解,今天趁着这个时间整理一下 许多实际问题抽象出来的数据结构往往是二叉树的形式,即使是一般的树也能简单地转换为二叉树,而且二叉树的存储结构及其算法都较为简单,因此二叉树显得特别重要.     二叉树(BinaryTree)是n(n≥0)个结点的有限集,它或者是空集(n=0),或者由一个根结点及两棵互不相交的.分别称作这个根的左子树和右子树的二叉树组成.     这个定义是递归的.由于左.右子树也是二叉树, 因此子树也可为空树.下图中展现了五种不同基本形态的二叉树.…

思路1:可以用建树来做 由于是先序遍历,所以直接先序建树就行了. #include<iostream> #include<cstdio> #include<cstring> using namespace std; ; int a[maxn],n,num; ]; void build(int id) { int x; ) return ; scanf("%s",str); ]=='u') { scanf("%d",&x);…
