OOPs (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
OOPs focuses on creating objects that interact with each other to solve complex problems.
Key principles of OOPs include encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation involves bundling data and methods that operate on the data into a single unit (object).
Inheritance allo...
SOLID principles are a set of five design principles in object-oriented programming to make software more maintainable, flexible, and scalable.
Single Responsibility Principle (SRP) - A class should have only one reason to change.
Open/Closed Principle (OCP) - Software entities should be open for extension but closed for modification.
Liskov Substitution Principle (LSP) - Objects of a superclass should be replaceable with...
It was an half hour test 20 questions purely based on ML and statistical knowledge.
Precision and recall are evaluation metrics used in machine learning to measure the performance of a classification model.
Precision is the ratio of correctly predicted positive observations to the total predicted positive observations.
Recall is the ratio of correctly predicted positive observations to the all observations in actual class.
Precision is important when the cost of false positives is high, while recall is i...

Append adds a single element to a list while extend adds multiple elements.
Append adds the element as it is to the end of the list.
Extend takes an iterable and adds each element of the iterable to the end of the list.
Append can be used to add a single element to a list.
Extend can be used to add multiple elements to a list.
Example: list1 = [1, 2, 3], list2 = [4, 5], list1.append(4) will result in [1, 2, 3, 4], list1.ext

Use SELECT statement with DATE_FORMAT function in SQL to print date in desired format.
Use SELECT DATE_FORMAT(date_column, 'desired_format') FROM table_name;
Replace 'date_column' with the column containing the date data and 'desired_format' with the format you want to print the date in.
Example: SELECT DATE_FORMAT(date_column, '%Y-%m-%d') FROM table_name;

Machine learning is a branch of artificial intelligence that focuses on developing algorithms and models that can learn from and make predictions or decisions based on data.
Machine learning involves training algorithms to learn patterns from data and make predictions or decisions.
It can be supervised, unsupervised, or semi-supervised learning.
Examples include recommendation systems, image recognition, and natural langu
A cloud platform is a service that allows users to store, manage, and process data remotely.
Cloud platforms provide scalable and flexible storage solutions
They offer various services such as computing power, databases, and analytics tools
Examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform
A pointer is a variable that stores the memory address of another variable.
Pointers are used to access and manipulate memory directly.
They are commonly used in programming languages like C and C++.
Example: int *ptr; // declaring a pointer variable
