git pull
git pull is a command used to fetch the latest changes from a remote repository and merge them into the local branch. It combines two actions: git fetch (retrieves updates) and git merge (applies them). Developers use git pull to stay synchronized with team changes, avoid conflicts and ensure their local codebase remains up to date.

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.
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.
