MySQL
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.

DROP DATABASE in SQL
The SQL DROP DATABASE statement is a powerful command in SQL that is used to permanently delete an existing database from a system, including all its data, tables, views, indexes, stored procedures , constraints and any other elements that belong to it. Once executed, the database and all its contents are permanently deleted and cannot be recovered unless a backup is available. This command should be used with caution, because it permanently deletes the database and all its contents.
CREATE Database in SQL
A database is an organized collection of data stored in a computer system, designed to facilitate efficient data storage and retrieval. Different query languages can be used to create and manage databases and SQL is one such language. Creating a database in SQL is one of the first steps in setting up a structured environment to store and manage data efficiently. After creating a database you can start creating tables, views, stored procedures and other database objects within it.

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.
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.
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.

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.
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.
