Data Structure and Algorithms Interview Questions

Hash table is a data structure that stores data in key-value pairs. It is also named as a dictionary or associative array. It stores data in a way that enables lookup and insertion in constant O(1) time. These properties of a hash make it one of the most useful data structures in a programmer's toolbox.

Implementation of the hash quite the same in Ruby, Java, Python. We just need to understand Pros and Cons of using it.

Learn how it works.
