1func main() {2    fmt.Println(common.Sum(1, 2))3}4func Sum(a, b int) int {5}6This is because the common package is not imported in the main package. To import the common package, you need to add the following line to the top of the 1.go file:7import "common"8To import a package from a different directory, you need to add the following line to the top of the 1.go file:9import "path/to/package"10In the above code, you need to replace the path/to/package with the actual path of the package that you want to import. For example, if you want to import the common package from the directory /home/user/golang, you need to add the following line to the top of the 1.go file:11import "/home/user/golang/common"
