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. Although the hash function we used in Example 7.1 was easy to compute, using only the first character in an identifier is bound to have disastrous consequences. 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. おぎやはぎのありがとうびいき(仮)
