Go programs are compiled on the server by the Go 1.14.6 x64. The compiler is invoked with the following parameters:
go build %1

An example of solving a problem
A sample solution for the 1000. A + B problem in Go:
package main
import "fmt"
func main() {
   var a, b int
   fmt.Scan(&a)
   fmt.Scan(&b)
   fmt.Println(a + b)
}
A sample solution for the 1001. Reverse Root in Go:
package main
import "fmt"
import "math"
var a [262144]int64
func main() {
   n := 0
   for {
      var x int64
      k, _ := fmt.Scan(&x)
      if k != 1 {
         break
      }
      a[n] = x
      n++
   }
   for n > 0 {
      n--
      fmt.Printf("%.4f\n", math.Sqrt(float64(a[n])))
   }
}
More effective solution of the same problem:
package main
import "os"
import "fmt"
import "math"
import "bufio"
import "strings"
import "strconv"
func main() {
   in := bufio.NewReader(os.Stdin)
   out := bufio.NewWriter(os.Stdout)
   text, _ := in.ReadString(0)
   a := strings.Fields(text)
   for i := len(a) - 1; i >= 0; i-- {
      f, _ := strconv.ParseFloat(a[i], 64)
      fmt.Fprintf(out, "%.4f\n", math.Sqrt(f))
   }
   out.Flush()
}
