structure's Introduction

structure

记录自己数据结构的学习过程

Stack

基于数组实现和基于链表实现的比较

基于数组实现

  • 每个操作都是常数时间开销
  • 每隔一段时间倍增操作的开销较大
  • n个操作的任意序列的平摊时间开销为O(n）

基于链表实现

  • 栈规模的增加和减小都很简洁
  • 各个操作都是常数时间开销
  • 每个操作都需要额外的空间和时间开销来处理指针

二叉树

类型

  • 严格二叉树：每个结点要么有两个孩子，要么没有孩子
  • 满二叉树:每个结点恰好有两个孩子结点且所有叶子结点在同一层
  • 完全二叉树

通用数

  • 同一个双亲结点（兄弟）的孩子结点从左至右排列
  • 双亲结点只指向第一个孩子结点，删除从双亲到其他孩子结点的连接

二叉搜索树(二叉排序树)

  • 一个结点的左子树只能包含键值小于该结点键值的结点
  • 一个结点的右子树只能包含键值大于该结点键值的结点
