Folding method in hashing
WebThe folding method for constructing hash functions begins by dividing the item into equal-size pieces (the last piece may not be of equal size). These pieces are then added together to give the resulting hash value. For example, if our item was the phone number 436-555-4601, we would take the digits and divide them into groups of 2 (43,65,55,46 ... WebHash Functions (continued) • Folding –In folding, the keys are divided into parts which are then combined (or “folded”) together and often transformed into the address –Two types …
