二叉搜索树(Binary Search Tree)是一种特殊的二叉树,支持多种动态集合操作,如 Search、Insert、Delete、Minimum 和 Maximum 等。 二叉查找树要么是一棵空树,要么是一棵具有如下性质的非空二叉树: 若左子树非空,则左子树上的所有节点的关键字值均小于根节点的关键字值。 若右子树非空,则右子树上的所有节点

BST树,英文全称:Binary Search Tree,被称为二叉查找树或二叉搜索树。 如果一个二叉查找树非空,那么它具有如下性质: 1.左子树上所有节点的值小于根节点的值,节点上的值沿着边的方向递减。 2.右子树上所有节点的值大于根节点的值,节点上的值沿着边的方向递增。

pynd is a command line utility for searching the Python abstract tree to easily find what you are looking for. It is a bit like using grep, but it understands Python syntax and structure. This means you can search for classes, functions or just within docstrings without relying on regular ...
