Array List
An ArrayList is a dynamic, resizable array-based data structure that allows storing elements in an ordered collection. It grows automatically when more space is needed and provides fast access using indexes. ArrayLists support insertion, removal and searching operations. They are commonly used when flexible, dynamic storage is required compared to fixed-size traditional arrays.

Min refers to the minimum value in a given set of numbers or elements. In programming and mathematics, the min function identifies the smallest value among inputs, such as min(a, b) or min(array). It is commonly used in comparisons, optimization problems, data analysis and algorithms to determine the lowest or least outcome efficiently.
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.
PostgreSQL is a free, open source relational database management system. It was initially developed as a successor of the Ingres database
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.
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.
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.
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.
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.
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.
