    -Dynamic programming is a strategy used to improve the runtime complexity of algorithms by breaking them down into simpler subproblems and storing the solutions to these subproblems to avoid redundant computations.

  • How does GitHub facilitate collaboration in software development?

    -GitHub is a platform built on top of Git, a version control system, that allows developers to upload their code, track changes through commit history, and collaborate through issues and pull requests, enabling many contributors to work on a single project.

  • What is the significance of open-source software and how does it benefit the development community?

    -Open-source software allows the source code to be freely accessible and modified by anyone. This encourages collaboration, as many developers can contribute to a single project, leading to more robust, secure, and innovative solutions.

  • Why is it necessary to document code, especially when dealing with complex or unfamiliar code?

    -Documenting code is necessary to provide a clear understanding of what the code does, making it easier for others to read, maintain, or enhance the code, especially when dealing with complex or unfamiliar code.

  • What is a batch script and how does it function?

    -A batch script is a type of script file in DOS, OS/2 and Windows. It consists of a series of command lines to be executed by the command-line interpreter. In the context of the script mentioned, it is used to launch Visual Studio Code in development mode with specific settings.

  • How does the Visual Studio Code application, being open source, contribute to its development and improvement?

    -As an open-source application, Visual Studio Code benefits from a community of developers who can view, modify, and enhance the codebase. This collaborative approach allows for continuous improvement, the quick resolution of issues, and the incorporation of new features.

  • What is the importance of proper indentation in code and how does it affect the execution of the code?

    -Proper indentation is crucial in code as it improves readability and helps in understanding the structure of the code. In some programming languages, incorrect indentation can lead to syntax errors or runtime errors, as seen in the example where the lack of proper indentation caused a runtime error.
