Q1. Interface in golang
Ans. 
Interfaces in Golang define a set of methods that a type must implement.
• Interfaces are a way to specify behavior of an object.

• A type satisfies an interface if it implements all the methods of that interface.

• Interfaces allow for polymorphism in Golang.

• Example: type Writer interface { Write([]byte) (int, error) }

• Example: type MyWriter struct {} func (mw MyWriter) Write(data []byte) (int, error) { return len(data), nil }
