In generics, an interface can also be a set of types. So I'm saying that the ordered interface is either an integer, a float 64, or a string. And now I can use this type in my function. So I'm writing a minimum function, which has a type T, which is a generic type, with the constraint that it is ordered. And from here, we continue as usual. We're saying that minimum gets a slice of T and return of T is single value and a possible error. First we check if the length of value is zero, we need to return the zero value for T and an error. So we define a viable zero T and then return it and an error saying minimum of an empty slice. If there are values, we start with the initial values then do a follow, compare, and assign to the minimum value. And finally, we turn the…
