Binary Search
Binary search is an efficient algorithm used to find an element in a sorted array or list by repeatedly dividing the search range in half. It compares the target value to the middle element, narrowing the search to either the left or right half. It runs in O(log n) time complexity.

A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views, and other objects. The data are typically organized to model aspects of reality in a way that supports processes requiring information. Use this tag if you have questions about designing a database.
math tag that is used for mathematical operations Math is the study of numbers, shapes, patterns and logical relationships. It provides tools for problem-solving, measurement and analysis across science, technology, engineering and daily life. Math includes fields like algebra, geometry, calculus and statistics. It builds critical thinking skills and forms the foundation for computing, algorithms, data science and modern technological advancements.
A method is a block of code that performs a task.
MySQL is an open-source relational database management system widely used for storing and managing structured data. It supports SQL for querying, updating and controlling data efficiently. Known for reliability, speed and scalability, MySQL powers web applications, enterprise systems and cloud platforms. It is commonly used with PHP, Java, Python and modern application stacks like LAMP and MERN.
System design is the process of defining the architecture, components, modules, interfaces and data flow of a system to meet specific requirements. It focuses on creating scalable, efficient and maintainable solutions, covering both high-level design (HLD) and low-level design (LLD). Essential for building reliable, high-performance software systems.
A challenge is a task, problem or situation that tests a person’s skills, knowledge or determination. Challenges encourage growth by pushing individuals beyond their comfort zones and inspiring creative problem-solving. In learning, technology and work environments, challenges help improve abilities, build confidence and lead to meaningful achievements through consistent effort and resilience.
Software design is the process of planning and structuring a software system’s architecture, components, interfaces, and data flow to meet functional and non-functional requirements. It ensures scalability, maintainability and performance. Key approaches include modular design, object-oriented design and architectural patterns like MVC and microservices for efficient, reliable software development.
C# (C-Sharp) is a modern, object-oriented programming language developed by Microsoft for building secure, scalable applications. It runs on the .NET platform and supports features like strong typing, garbage collection, LINQ, async programming and cross-platform development. C# is widely used for web, desktop, game development (Unity), cloud services and enterprise-level software solutions.
DSA (Data Structures and Algorithms) is a fundamental concept in computer science that focuses on efficiently storing, organizing and processing data. Data structures like arrays, linked lists, stacks and trees manage data, while algorithms provide step-by-step solutions to problems. Mastering DSA is essential for writing optimized, scalable and high-performance code.
