reverse hash

Hash Hash, the general translation to do "hash", there is a direct transliteration of "hash", is the arbitrary length of the input (also known as pre-mapping, pre-image), through the hash algorithm, transformed into a fixed-length output,

One, the structure of the Hash indexThe hash index consists of the buckets set, and index Key is mapped by the hash function, resulting in a hash value, which is filled into the corresponding bucket, and the hash value of each bucket is different.

One, what is Perl Hash A hash is a data structure, and a similar array, that can be stored in or retrieved from a value. However, unlike arrays, the index is not a number, but a name. That is, the index (here, we call it key) is not a number but an
