前几天复习了一下对分查找(Binary Search),它提供了在O(log N)时间内的 Find (查找操作),先来看看对分查找的叙述要求: 给定一个整数 X 和整数 ,后者已经预先排序,并且已经在内存中,求使得 的下标 i ,如果 X 不在数据之中,则返回 i = -1。 来看看实现源码: 1 2 3 4 5 6 7 8 9 10 11 12 1...
二叉搜索树(binary search tree)能够高效的进行插入, 查询, 删除某个元素,时间复杂度O(logn). 简单的实现方法例如以下. 代码: /* * main.cpp * * Created on: 2014.7.20 * Author: spike */ /*eclipse cdt, gcc 4.8.1*/ #include <stdio.h> #include <queue> #include <vector> #include <function...

2二叉排序树(binary search tree) 之前我们遇到的 vector list queue 这都是线性结构。 也就是从头到尾,逻辑上一个挨着一个的结构。 这种结构最大的缺点就是元素数量变的很多之后,就像一个很长的绳子,或者钢筋,中间插入元素和删除元素都非常的费劲。
Binary Search is a searching algorithm for finding an element's position in a sorted array. In this tutorial, you will understand the working of binary search with working code in C, C++, Java, and Python.
In computer science, binary search is a search algorithm that finds the position of a target value within a sorted array. 二分搜索算法 在对数组的搜索算法之中,最朴素的思想就是从数组的第一个元素开始,逐个将数组中的元素与目标值做比较,以得到用户期望的元素下标,因此朴素的搜索算法是一种O(N)时间的...
