Hash Table in Data Structure | Definition, Applications & Example

Govind Pothuraju on Instagram: "Day 20/200: How HashMap Works Internally HashMap is one of the most powerful data structures in coding interviews & real-world systems. Here’s how it works under the hood: ✅ Hashing: Key → Hash function → Index in array (bucket). ✅ Collision handling: Chaining (LinkedList/Tree in Java) or Open addressing. ✅ Time complexity: O(1) average for put/get, O(n) worst-case. ⚡ Mastering HashMap internals is a must for interviews — it shows depth, not just coding ability.

Nilesh Hadalgi | Techie Programmer on Instagram: "A hashtable is a data structure that stores key–value pairs and enables fast data access. It uses a hash function to convert each key into an index in an underlying array, allowing average-case constant time complexity for insert, search, and delete operations. Collisions, where multiple keys map to the same index, are handled using techniques like chaining or open addressing. Hashtables are widely used for implementing dictionaries, caches, and
