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 distributed system is a network of independent computers that work together to achieve a common goal. These systems share resources, process tasks in parallel and ensure fault tolerance. Used in cloud computing, databases and large-scale applications. They improve scalability, reliability and performance by distributing workloads across multiple nodes efficiently.
In databases, a query is a request to retrieve, insert, update or delete data. Written in SQL (Structured Query Language), queries can be simple, like fetching all rows from a table, or complex, involving joins, conditions and aggregations. They are essential for interacting with and managing database information efficiently.
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.
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.
Artificial Intelligence (AI) is the simulation of human intelligence in machines, enabling them to think, learn and make decisions. It powers systems to solve problems, recognize patterns, understand language and adapt over time. AI is used in various fields, including robotics, healthcare, finance and everyday applications like virtual assistants.
Technical Interview is a structured assessment where employers evaluate a candidate’s technical skills, problem-solving ability and practical knowledge related to a specific role. It typically includes coding challenges, system design questions, debugging tasks and discussions about past projects. The goal of a technical interview is to measure how effectively a candidate can apply their technical expertise to solve real-world problems.
This tag is used to understand a basic part of the language.
Coding Interview is a technical evaluation where candidates solve programming problems to demonstrate their problem-solving skills, data structure and algorithm knowledge and coding proficiency. It typically includes writing optimized code, explaining logic and analyzing time and space complexity to assess real-world programming ability.
A structured conversation where one participant asks questions and the other provides answers of those questions.
Coding problems are exercises designed to test a programmer’s ability to write logic, solve challenges and apply algorithms or data structures. They help improve problem-solving skills, logical thinking and coding efficiency. Common in interviews and competitive programming, coding problems range from simple tasks to complex algorithmic challenges, preparing developers for real-world software development scenarios.
