What is the primary advantage of using a Hash Table?

The primary advantage of using a hash table is its ability to allow for quick data retrieval. This efficiency arises from the hash table's underlying data structure, which uses a hash function to map keys to their associated values. When a key is provided, the hash function computes its hash code, which indicates the index where the corresponding value is stored. This enables average-case time complexity of O(1) for operations like insertion, deletion, and search, making hash tables extremely effective for scenarios where rapid access to data is crucial.

In contrast, sorting data quickly, minimizing memory usage, and supporting recursion are not inherent benefits of hash tables. Sorting typically requires different algorithms and data structures, memory usage can vary based on the implementation and load factor, and recursion pertains more to function calls than the data storage mechanisms provided by hash tables.
