What are you looking for that isn't in those?Sat, 11 Apr 2026 22:10:00 GMThttps://www.zhihu.com/question/26762707提到hash，相信大多数同学都不会陌生，之前很火现在也依旧很火的技术区块链背后的底层原理之一就是hash，下面就从hash算法的原理和实际应用等几个角度，对hash算法进行一个讲解。 1、什么是Hash Hash也称散列、哈希，对应的英文都是Hash。Mon, 09 Mar 2026 19:57:00 GMThttps://www.zhihu.com/question/21801702由于他的调皮，导致客户挑妹纸的时间大幅延长，从10秒到了800秒。 在代码中，一般都有一些比较复杂的算法去运算而得出这个hash值，一旦破解了这个算法，就又可以调皮啦。 在JAVA中，hash算法在HashMap中有体现，有兴趣的可以去看看源码。Thu, 16 Apr 2026 11:13:00 GMThttps://www.zhihu.com/question/20820286来分享下鹅厂 WXG 后开开发工程师 foxxiao对于 Hash的一些认识。 本文对完美 Hash 的概念进行了梳理，通过 Hash 构建步骤来了解它是如何解决 Hash 冲突的，并比较了 Hash 表和完美 Hash 表。下面介绍常见的 Hash 与 Perfect Hash 函数及它们在不同场景的应用。 散列函数（英语：Hash function）又称散列算法、哈希 ...Sat, 11 Apr 2026 20:37:00 GMThttps://www.zhihu.com/question/476720214比如在Java中，一个对象的hash code 是一个32位的二进制数，它是根据对象的属性值简单计算出来的，这个hash code是所有对象的属性值一起混淆的结果。 再比如，在某些集合和数据库中，常常使用一个对象或者字段的hash code来建立索引，方便进行数据查找。Mon, 30 Mar 2026 15:22:00 GMThttps://cs.stackexchange.com/questions/125572/what-is-the-best-hash-functions-for-millions-of-string-keysPJW hash/ElfHash is popular for programming languages because it was designed to handle the above cases well. If you do have millions of keys, probably the best way to do it is to measure the hash chain lengths and see if they follow a Poisson distribution.Mon, 13 Apr 2026 23:41:00 GMThttps://cs.stackexchange.com/questions/154265/time-complexity-analysis-for-searching-in-a-hash-table0 I want to analyse the time complexity for Unsuccesful search using probabilistic method in a Hash table where collisions are resolved by chaining through a doubly linked list. And the doubly linked list is kept in sorted order (Ascending).Sun, 05 Apr 2026 21:56:00 GMThttps://cs.stackexchange.com/questions/167129/how-to-select-hash-functions-for-cuckoo-hashingGreat question, well, actually a family of questions :) Let's start with Cyckoo hashing. I checked the Wikipedia article to be sure, and indeed it doesn't mention any families. So, the answer is simple - you just use 2 hash functions, whose avalanche and other properties are good enough for you. These 2 functions are fixed for each cuckoo hashtable, providing 2 allowed positions for each key ...Wed, 01 Apr 2026 21:53:00 GMThttps://www.zhihu.com/question/439413141哈希表的定义 (Definition) 哈希表（Hash Table），也称为散列表，是一种实现 字典（Dictionary） 或 映射（Map） 抽象数据结构的方法。 核心思想：它将数据的 键（Key） 通过一个特定的函数映射到一个 数组（Array） 的索引（Index）上，从而实现对数据的快速访问。Sat, 28 Mar 2026 11:21:00 GMThttps://cs.stackexchange.com/questions/168888/understanding-polynomial-rolling-hash-function-by-modular-arithmeticI was learning the Polynomial Hash function in python, the one used in Rabin Karp Algorithm This is the implementation I was taught: def GivenHash(S,p=113,x=10): hash = 0 for i in range(len(S)-...Sat, 14 Mar 2026 22:43:00 GMT
