Hash folding
WebHere p is a constant and the hash function range is the integers 0, 1, 2, ..., 2 p-1. Folding In this method the key is interpreted as an integer using some radix (say 10). The integer is divided into segments, each segment except possibly the last having the same number of digits. These segments are then added to obtain the home address.

Free shipping for many products! A hash function takes a key as an input, which is associated with a datum or record and used to identify it to the data storage and retrieval application. The keys may be fixed length, like an integer, or variable length, like a name. In some cases, the key is the datum itself. The output is a hash code used to index a hash table holding the data or records, or pointers to them. A hash function may be considered to perform three functions:
WebHash Table Issues n Underlying data-structure q fixed length array, usually of prime length q each slot contains data n Addressing q map key to slot index (hash code) q use a function of key n e.g., first letter of key n What if we add ‘cap’? q collision with ‘coat’ q collision occurs because hashcode does not give unique slots for each key.
WebA hash function, f, transforms an identifier, x, into a bucket address in the hash table. We want to hash function that is easy to compute and that minimizes the number of collisions.
