Issue 1: Missing docstring for internode_combine method

[PrinceSajjadHussain]

The Buffer class has an internode_combine method that lacks a docstring. A clear docstring is crucial for understanding the purpose, arguments, and return values of this method, especially given that it's an internal implementation detail intended for use by the combine method. Adding a detailed docstring will improve code readability and maintainability.
