WebExplanation: The above Java program implements the Index Mapping (or Trivial Hashing) technique to insert and search elements in a hash table. The program initializes the hash table with all elements set to -1, and uses a hash function that maps an element to an array index by taking the modulus of the element with the table size. WebThe element is stored in the hash table where it can be quickly retrieved using hashed key. hash = hashfunc (key) index = hash % array_size. In this method, the hash is independent of the array size and it is then reduced …
