Can you elaborate on the use of the "ref" keyword in programming, specifically in the context of C#? How does it differ from the "out" keyword, and in what scenarios would you choose to use it? Understanding its functionality is crucial for mastering parameter passing in C#, so I'd appreciate a clear and concise explanation.

The `ref` keyword, in programming languages such as C#, serves as a powerful tool for achieving this. When a parameter is passed with the `ref` keyword, it signifies that the actual memory location of the variable is being passed, not just its value.

This mechanism allows the called method to directly access and modify the original data, rather than operating on a copy of it. Consequently, any changes made to the parameter within the method are reflected outside of the method scope.

One of the key advantages of using `ref` parameters is efficiency, as it avoids the overhead of creating and copying large data structures. Additionally, it enables more flexible and dynamic programming patterns.
