Hashmap is a data structure that stores key-value pairs and allows constant time access to values based on their keys.

Collisions can occur when multiple keys map to the same index, which can be resolved using techniques like chaining or open addressing.
Examples of hashmap implementations include Java's HashMap class and Python's dict type.

There are three types of machine learning: supervised, unsupervised, and reinforcement learning.
Supervised learning involves labeled data and predicting outcomes based on that data.
Unsupervised learning involves finding patterns in unlabeled data.
Reinforcement learning involves an agent learning to make decisions based on rewards and punishments.
Examples of supervised learning include image classification and spam filt...

It focuses on encapsulation, inheritance, and polymorphism
It helps in creating modular, reusable, and maintainable code
