Solution in Go (1.6) (judge verdict: Accepted)

package main

import(
	"fmt"
  	"bufio"
  	"os"
  	"strings"
  	"strconv"
)

var (
  A string
  
)

func main(){
  var sc = bufio.NewScanner(os.Stdin)
  sc.Scan()
  A = sc.Text()//string
  B := strings.Split(A, " ")
  a, _ := strconv.Atoi(B[0])
  b, _ := strconv.Atoi(B[1])
  c, _ := strconv.Atoi(B[2])
  total := a+b+c
  
  if total == 17 {
    fmt.Println("YES")
  }else{
    fmt.Println("NO")
  }
}
