Describe and Add Three Different Types

Write two function templates that each take THREE type parameters A, B and C:

- void describeThree(A a, B b, C c): prints the three values separated by , (comma and space) followed by a newline - auto sumThree(A a, B b, C c): returns a + b + c, letting auto pick the result type

Each type parameter is deduced from its own argument, so all three may differ. The tests call describeThree(1, 2.5, 'z') and describeThree(std::string("id"), 7, true) (a bool prints as 1), then print sumThree(1, 2, 3), sumThree(1, 2.5, 3) and sumThree(0.25, 1, 0.5), each result on its own line.

Do NOT write a main function.
