二叉树(Binary Tree)是最简单的树形数据结构,然而却十分精妙。其衍生出各种算法,以致于占据了数据结构的半壁江山。STL中大名顶顶的关联容器——集合(set)、映射(map)便是使用二叉树实现。由于篇幅有限,此处仅作一般介绍(如果想要完全了解二叉树以及其衍生出的各种算法,恐怕要写8~10篇)。
这大致就是我的思路,我发现我的思路跟网上其他人的思路差不多,为了让代码漂亮一点,我决定用max这个STL里面的函数 classSolution {public:intmaxPathSum(TreeNode *root) {//Start typing your C/C++ solution below//DO NOT write int main() functioninttmp=-99999999;if(!root)return0; maxPathSum2(root,...
and each vertex is either a leaf (and doesn't have children) or an inner node (and has exactly two children). All leaves of a complete binary tree have the same depth (distance from the root). Sonis a number such thatn + 1 is a power of 2. ...
二叉搜索树(Binary Search Tree)不同于之前使用的线性结构,它是一种通过离散的多个点以指针的形式连接起来的树形结构。 二叉树由一个根节点和根节点下属的多层次的子结点构成,任意一个结点最多只能拥有两个子结点,即左右子结点。基于此种特性,在实现二叉搜索树时,可以仅持有根节点,然后通过根节点去递归...
