Hash tables are a data structure that utilizes hash functions to map keys to specific indices within a table, enabling efficient storage and retrieval of key-value pairs. Hashing allows for constant time complexity (O(1)) for search, insertion, and deletion operations in ideal scenarios, making it valuable for applications that prioritize quick data access. Collision resolution techniques, such as chaining and open addressing, are employed to handle situations where multiple keys map to the same index. Maintaining an optimal load factor, typically below 0.75, is crucial for preventing excessive collisions and ensuring efficient performance. Hash tables are widely used in various applications, including database indexing, caching systems, and compilers.
