(1),满二叉树(full binary tree) 每个节点都有0个或2个子节点的二叉树称为满二叉树。 满二叉树除叶子节点以外,所有节点都有两个子节点。 (2),完美二叉树(perfect binary tree) 所有的叶子节点都在同一层。 所有内部节点都必须有两个子节点。 (3),完全二叉树(complete binary tree) 完全二叉树除了最后一层...
Arrays are a data structure, just like lists. With a number of objects of different data types, Python arrays can be repeated and have several built-in functions to handle them. Such conceptual questions play a vital role in Python data science interview questions. So keep this in mind when...
树的高度(Height of tree):根节点到叶子节点的最长距离。 节点的层级(Level):该节点的父节点数量+1。 节点的度(Degree):该节点的子节点数量。 二,二叉树的基础概念 每个节点最多有两个子节点的树被称为二叉树。 在给定的二叉树中,任何级别的最大节点数为2l-1,其中"l"是级别编号。

This image below should help you to feel the difference between tree and list representation of the heap and (note, that this is a max heap, which is the inverse of the usual min-heap!): In general, heap data structure is different from a sorted list in that it sacrifices some informat...
图没有起始位置和终止位置,是由顶点和边组成的一种非线性数据结构。 2.图结构的常见概念(先大概了解一下,后面可以结合图示对照看看): 顶点(Vertex/Node):顶点又称节点,是图的基础部分。 边(Edge):两个顶点之间的连线。 权重(Weight):边上可以附带的权重大小,用来表示从一个顶点到另一个顶点的成本。
Another way to remove punctuation from a string is to use thestr.translate()andmaketrans()methods of the string data structure in Python. The maketrans() method returns a translation table that can be used with thestr.translate()method to replace specified characters. ...
