Ainult 6. koodirida muutmisega (ilma funktsiooni allkirja muutmiseta) on võimalik juurde pääseda funktsiooni sees lisatud elementidele (kolmik ja nelik)?

In Go, if elements (for example, numbers 3 and 4) are added inside a function to a local slice variable, it is generally not possible to access them directly from outside by only changing the sixth line of code and without changing the function's signature. This is because local variables of a function exist only within its scope.

However, if the sixth line is responsible for the return value or for modifying the passed parameter (for example, a slice), then it can be changed to return or store a reference to these elements. For example, if the function returns a slice, the sixth line can be modified to return the slice with the added elements:

func example() []int {
    s := []int{1, 2}
    s = append(s, 3, 4) // sixth line
    return s
}

In this case, by only changing the sixth line, we ensure access to the new elements through the returned value. If the function does not return a slice and accepts it as a value, then it is not possible to access the added elements without changing the signature.
