二叉树(Binary Tree)是一种树形数据结构,由节点构成,每个节点最多有两个子节点:一个左子节点和一个右子节点。 publicclassTreeNode{intval; TreeNode left; TreeNode right; TreeNode(intval) {this.val = val; } } 基本概念 "二叉树"(Binary Tree)这个名称的由来是因为二叉树的每个节点最多有两个子节点,...

二叉树:在 计算机科学中,二叉树(英语:Binary tree)是每个节点最多只有两个分支(即不存在分支度大于2的节点)的树结构。通常分支被称作“左子树”或“右子树”。二叉树的分支具有左右次序,不能随意颠倒。学…
