15 examples of both input and output?

To provide 15 examples of both input and output, we can consider a variety of contexts such as programming, natural language processing, and data conversion. For instance, in a programming context, an input could be a string "Hello", and the output could be its length, which is 5. Similarly, for a data conversion example, an input of "100" (in binary) would output "4" (in decimal). If you need specific examples in a particular domain, please let me know!
