Webrely on identifier comparisons to perform a search, hashing relies on a formula called the hash function. We divide our discussion of hashing into two parts: static hashing and dynamic hashing. Static Hashing Hash Tables In static hashing, we store the identifiers in a fixed size table called a hash table. We use an arithmetic function, f,
