Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.

• Start from the first element and compare it with the next element

• If the next element is smaller, swap them

• Repeat this process for all elements in the array

• Continue this process until no more swaps are needed

A program to print all prime numbers

• Take input from user for range of numbers

• Loop through the range and check if each number is prime

• Print the prime numbers

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

• Hashmap uses a hash function to map keys to indices in an array.

• 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.

Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.

• Inheritance allows code reuse and promotes code organization.

• The existing class is called the parent or superclass, and the new class is called the child or subclass.

• The child class inherits all the properties and methods of the parent class and can also add new properties and methods.

Recursion is a process in which a function calls itself. Inheritance is a mechanism in OOP where a class inherits properties of another class. Heap is a region of memory used for dynamic memory allocation.

• Recursion can be used to solve problems that can be broken down into smaller sub-problems.

• Inheritance allows for code reuse and helps in creating a hierarchy of classes.

• Heap is used for dynamic memory allocation in la...read more

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...read more

OOPs stands for Object-Oriented Programming. It is a programming paradigm that uses objects to design applications.

• OOPs is based on the concept of classes and objects

• It focuses on encapsulation, inheritance, and polymorphism

• It helps in creating modular, reusable, and maintainable code

• Examples of OOPs languages are Java, C++, Python, etc.

SDLC stands for Software Development Life Cycle, a process used to design, develop, and maintain software.

• SDLC is a structured approach to software development

• It involves several phases such as planning, analysis, design, implementation, testing, and maintenance

• Each phase has its own set of activities and deliverables

• SDLC helps ensure that software is developed efficiently, on time, and within budget

• Examples of SDLC mo
