While Buffer.clear() is operating correctly, why isn't buffer.pop() functioning properly?

edit

It is difficult to determine the exact reason without additional information, but here are a few possible reasons:

1. The buffer may not contain any values or elements to pop out. If the buffer is already empty, calling buffer.pop() will not do anything.

2. The buffer may not be properly initialized or instantiated. If the buffer is not properly created or initialized, it may not have the required methods or functions to function properly.

3. There may be a logical error in the code. There may be a bug or an error in the code that could be causing buffer.pop() to not function properly.

4. The buffer may not be implemented correctly. The buffer implementation may not be correct, which could be causing buffer.pop() to behave unexpectedly.
