`package main` default package declaration	`import "fmt"` loads `fmt` package to operate on strings (and print them)
`fmt.Sprintf(` formats given string based on a given template and return result	`%s is %d country!` template string to format variables (first - string placeholder, second - decimal placeholder)
`a, b` variables to use for formatting (`a` goes to the first placeholder, `b` goes to then second)	`fmt.Println` prints specified string

package main
import "fmt"

func main() {
  a := "Ukraine"
  b := 1
  res := fmt.Sprintf("%s is %d country!", a, b)
  fmt.Println(res)
}

Ukraine is 1 country!
