Work Step by Step

In both a hash file and a homogeneous two-dimensional array, the hash function and the address polynomial play similar roles in determining the location of data storage. They both help in mapping a key or index to a specific location in memory or storage space. The hash function computes a hash value from the key, which is then used to determine the storage location in the hash file. Similarly, the address polynomial, often used in hashing techniques like open addressing, calculates an address from the key to find the storage location in the array. Both functions essentially serve as a means to efficiently locate and access data within their respective data structures.
