【C/C++ 基础算法】 C/C++ 位图算法的使用

C/C++ 位图算法 1. 什么是位图算法位图算法（Bitmap Algorithm）是一种在计算机科学和数据结构中用于高效地管理位（bit）的算法。它通常用于快速检索和存储数据。位图算法在内存使用上非常高效，因为它每个元素只使用一个位。 In computer science, a bitmap is a mapping from some domain to bit...

【C++杂货铺】再谈哈希算法：位图 | 布隆过滤器 | 哈希切分

一、位图1.1 一道面试题给40亿个不重复的无符号整数，没排过序。给一个无符号整数，如何快速判断一个数是否在这40亿个数中。解决方案：遍历：遍历这40亿个整数，去判断该数是否在这40亿个整数中。时间复杂度是 O ( N ) O(N)O(N)。set：用 set 将这40亿个整数存起来，然后去判断这个数是否在 set 中。时间复杂度是 O ( l o g 2 N ) O(log2^N)O(log2....
