While a type parameter’s constraint typically represents a set of types, at compile time the type parameter stands for a single type – the type provided as a type argument by the calling code. If the type argument’s type isn’t allowed by the type parameter’s constraint, the code won’t compile.

Keep in mind that a type parameter must support all the operations the generic code is performing on it. For example, if your function’s code were to try to perform string operations (such as indexing) on a type parameter whose constraint included numeric types, the code wouldn’t compile.

pe constraint that acts as a kind of meta-type for the type parameter. Each type constraint specifies the permissible type arguments that calling code can use for the respective type parameter. <span>While a type parameter’s constraint typically represents a set of types, at compile time the type parameter stands for a single type – the type provided as a type argument by the calling code.

For example, if your function’s code were to try to perform string operations (such as indexing) on a type parameter whose constraint included numeric types, the code wouldn’t compile. In the code you’re about to write, you’ll use a constraint that allows either integer or float types. Write the code Beneath the two functions you added previously, paste the following
