i have no doubts though that it is of highest quality too. this hash table implementation is currently hardwired to be used with string keys. it would be trivial to support other types too, but the more generic, the more messy the API becomes. see test.c for usage examples....
I just wanted a simple and straightforward hash table implementation that I could drop into my own C-based projects on whatever platform.I haven't implemented one of these before, so it may be super naive, but it does appear to work pretty well.NOTE...
Using the tabular approach for storing subproblems often works well with a bottoms up implementation of the algorithm. DP algorithms typically start by solving the smallest subproblems, storing the results, combining some of those, storing the results in a new level of the table, and so on, ...
(1) open addressing (开放定址法): 当发生冲突时,我们在hash table中查找下一个空的位置来存放发生冲突的key。这里介绍两种寻找的方式: (i) Linear Probing (线性探测): 相当于逐个探测hash table,直到查找到一个空的slot,把key存放在该位置。例如,发生冲突的hash value是h, 后面查找的顺序为h+1, h+2, ...
Implementation of hash tables with separate chaining (open hashing) Assumption Hash function will return an integer from 0 to 19. vector<string>hashTable[20];inthashTableSize=20; Insert voidinsert(strings){// Compute the index using Hash Functionintindex=hashFunc(s);// Insert the element in ...
h["b"] = "c"; 1. 2. 3. 4. 5. 6. h.Contains("a"); h.Remove("a"); h.ContainsKey("b"); 构造函数: // Constructs a new hashtable. The hashtable is created with an initial // capacity of zero and a load factor of 1.0. ...
一致性哈希算法在 1997 年由麻省理工学院提出,是一种特殊的哈希算法,在移除或者添加一个服务器时,能够尽可能小地改变已存在的服务请求与处理请求服务器之间的映射关系; 一致性哈希解决了简单哈希算法在分布式哈希表(Distributed Hash Table,DHT)中存在的动态伸缩等问题; ...
template<typename T, typename KEY, typename HASHFUNC, int LENGTH>class CSphOrderedHash; 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 最后一层终于看到基类了。 json 与 hash table 看到这里, 我们发现所有的节点都继承于 SmallStringHash_T 这个模板类。
The System.Collections.Hashtable Class The .NET Framework Base Class Library includes an implementation of a hash table in theHashtableclass. When adding an item to the Hashtable, you must provide not only the item, but the unique key by which the item is accessed. Both the key and item...
最近在学习CMU的15-445 DB课程,在做Project1的Extendible Hash Table的时候,由于是先看了课程,过了一个多星期才做的Lab,对extendible hash table只能说是知道大体的意思,并没有透彻的了解它,尤其是bucket指针和数据重分配这一部分,涉及到比较tricky的位运算,在一知半解的情况下实现它,完全没办法找到对应的bug,Con...
