Quick sort and Merge sort are popular sorting algorithms used to efficiently sort arrays of elements.
Quick sort: Divide and conquer algorithm, picks a pivot element and partitions the array around the pivot. Recursively sorts subarrays.
Merge sort: Divide and conquer algorithm, divides the array into two halves, recursively sorts the halves, and then merges them back together.
Example: Quick sort - [3, 6, 8, 10, 1, 2, 1]
Binary Search Tree is a data structure where each node has at most two children, with left child smaller and right child larger. Time complexity is O(log n) for search, insert, and delete operations.
Nodes have at most two children - left child is smaller, right child is larger
Search, insert, and delete operations have time complexity of O(log n)
Example: In a BST, if we search for a value, we can eliminate half of the r
HashMap is a data structure in Java that stores key-value pairs.
HashMap is part of the Java Collections framework.
Keys in a HashMap must be unique.
Values in a HashMap can be duplicated.
Example: HashMap
Example: map.put("John", 25);
Implementation of a linked list in code format
Define a Node class with data and next pointer
Create LinkedList class with methods like insert, delete, search
Handle edge cases like empty list, inserting at beginning/end
Interface defines only method signatures while abstract class can have method implementations.
Interface cannot have method implementations, only method signatures
Abstract class can have method implementations along with abstract methods
A class can implement multiple interfaces but can only inherit from one abstract class
Interfaces are used to achieve multiple inheritance in Java
Abstract classes can have constructors wh
Array is a fixed-size data structure while linked list is a dynamic data structure. ArrayList and LinkedList are implementations of List interface in Java.
Array is a contiguous block of memory with fixed size, while linked list is a collection of nodes where each node points to the next node.
ArrayList in Java is implemented using an array, which can dynamically resize itself. LinkedList is implemented using nodes with ...
Polymorphism is the ability of a single function or method to operate on different types of data.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: a superclass Animal with subclasses Dog and Cat. Both Dog and Cat can be treated as Animals.

EfficientNets are a family of convolutional neural networks that have been designed to achieve state-of-the-art accuracy with fewer parameters and FLOPS.
EfficientNets use a compound scaling method to balance network depth, width, and resolution for optimal performance.
They are based on a baseline network architecture called EfficientNet-B0, which is then scaled up to create larger models like EfficientNet-B1, Efficient...
Transformers architecture is a deep learning model that uses self-attention mechanism to process sequential data.
Transformers consist of an encoder and a decoder, each composed of multiple layers of self-attention and feed-forward neural networks.
Self-attention mechanism allows the model to weigh the importance of different input tokens when making predictions.
Transformers have achieved state-of-the-art performance in ...

Bias in ML refers to the systematic error in a model's predictions, leading to inaccurate results.
Bias is the algorithm's tendency to consistently learn the wrong thing by not taking all factors into account.
It can result from the data used to train the model being unrepresentative or skewed.
Bias can lead to unfair or discriminatory outcomes, especially in sensitive areas like hiring or lending decisions.
Examples inclu...
Regression in ML is a supervised learning technique used to predict continuous values based on input features.
Regression models establish a relationship between dependent and independent variables.
Common regression algorithms include linear regression, polynomial regression, and logistic regression.
Evaluation metrics for regression models include Mean Squared Error (MSE) and R-squared.
Example: Predicting house prices b...
