In data structure Hash, hash function is used to convert a string(or any other type) into an integer smaller than hash size and bigger or equal to zero. The objective of designing a hash function is to "hash" the key as unreasonable as possible. A good hash function can avoid collision...

A good hash functions should produce hash values that are evenly distributed over a fairly large range. The modulus is taken with the hash table size (a prime number) to find the ‘bucket’ to place each key into. The function should also be very fast, since it is called for each key ...
funcConvertIntToString(hashuint64,charsuint)string ConvertIntToString converts an integer geohash to the equivalent string geohash with chars characters. The provided integer geohash is interpreted to have 5*chars bits of precision. func ConvertStringToInt ...
哈希(hash)函数也称为消息摘要函数、单向散列函数或者杂凑函数,是一种将任意长度的消息压缩到某一固定长度(消息摘要的)的函数。 单向散列函数有一个输入和一个输出,其中输入称为消息(message),输出称为散列值(hash value)。单向散列函数可以根据消息的内容计算出散列值,而散列值就可以被用来计算消息的完整性,该过程...

Calculates JavaHash from a string, Byte, Short, Integer, Long. This hash function is neither fast nor having a good quality. The only reason to use it is when this algorithm is already used in another system and you have to calculate exactly the same result. ...
The default hashCode() function in inbuilt Java types (such as String, Integer, Long etc) does an excellent job in most cases. So it is highly advisable to use Java String or wrapper classes as the keys in the HashMap. Still, if we require to create a custom key class, the following...
convert the fetched objects into SHA-256 form and record the mapping in the bidirectional mapping table (see below for details). Pushes to a SHA-1 based server convert the objects being pushed into SHA-1 form so the server does not have to be aware of the hash function the client is ...
eg. Integer, String, Float, etc.. Currently, let us consider data elements of type integer. ...
