Queue
A queue is a linear data structure that follows the First In, First Out (FIFO) principle. Elements are added at the rear (enqueue) and removed from the front (dequeue), making it ideal for scheduling, task management and buffering. Common types include simple queue, circular queue, priority queue and deque.

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.
Application design is the process of planning and structuring an application’s architecture, user interface, data flow and functionality to meet user and business requirements. It involves decisions on technology stack, design patterns, scalability and security. Good application design ensures performance, maintainability and a seamless user experience across platforms and devices.
The two-pointer technique is an efficient algorithmic approach that uses two indexes to traverse data structures like arrays or strings. The pointers move toward each other, away from each other or in the same direction to solve problems involving searching, pair finding or window management. It reduces complexity, often turning O(n²) solutions into O(n), making it ideal for optimized problem-solving.
Max refers to the maximum value in a set of numbers or elements. In programming and mathematics, the max function identifies the largest value among inputs, such as max(a, b) or max(array). It is widely used in algorithms, data analysis, comparisons and decision-making processes to determine optimal or highest results 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.
Java is a high-level object-oriented programming language. it's firstly released by Sun Microsystems in 1995. Use this tag when you're having queries using or understanding the language. This tag is also applicable to Java libraries and frameworks.
PostgreSQL is a free, open source relational database management system. It was initially developed as a successor of the Ingres database
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.
Loop are a type of control flow structure in programming in which a series of statements may be executed repeatedly until some condition is met.
