Stack
A stack is a linear data structure that follows the Last In, First Out (LIFO) principle. Elements are added (push) and removed (pop) from the top, making it ideal for tasks like expression evaluation, backtracking and function call management. Common implementations include arrays and linked lists for efficient data handling.

String is a data type used in most of the programming language. String is a sequence of characters and can contain letters, spaces , symbols ,numbers etc. commonly used for text, though sometimes for arbitrary data.
SQL stands for Structured query language. It is a programming language for storing and processing information in a relational database. It is standard language for accessing and manipulating databases.
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.
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.
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.
This tag is used to understand a basic part of the language.
PostgreSQL is a free, open source relational database management system. It was initially developed as a successor of the Ingres database
Git is a distributed version control system used to track changes in code, collaborate with teams and manage project history. It allows developers to work independently on branches, merge updates and revert to previous versions when needed. Git ensures code integrity, supports parallel development, and is widely used in software engineering for efficient source code management and collaboration.
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.
Sorting is the process of arranging data in a specific order, typically ascending or descending. It helps improve search efficiency, data organization and overall algorithm performance. Common sorting algorithms include Bubble Sort, Merge Sort, Quick Sort and Insertion Sort. Sorting is widely used in databases, applications and system processes to manage and analyze information effectively.
