散列函数源代码,散列表通常是关键字和值对应的数据结构,散列函数用于把关键字映射到相应的数组索引号,由于散列表中每个元素访问到的概率不同,所以应该选用不同的散列函数,以提高程序的查找效率.-Hash function source code, hash table is usually the value of keywords and corresponding data structure, hash function used for the keywords mapped to the corresponding array index number, because each element in the hash table the probability of access to different, so should choose a different hash function in order to improve the efficiency of search procedures.
