WebHashing is the transformation of a string of characters into a usually shorter fixed-length value or key that represents the original string. Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. I think this may clear your doubt. Share WebDouble Hash Function. The first hash function determines the initial location to located the key and the second hash function is to determine the size of the jumps in the probe sequence. The following function is an example of double hashing: h (key, i) = (firstHashfunction (key) + i * secondHashFunction (key)) % tableSize.
