For problem statement at 0-999/500-599/510-519/519/problemB.txt this is a correct solution, but verifier at 0-999/500-599/510-519/519/verifierB.go ends with case 1 failed: expected "17 13" got "17\n13"
input:
3
13 17 8
13 8
8
exit status 1 can you fix the verifier? package main

import (
	"bufio"
	"fmt"
	"os"
)

func main() {
	reader := bufio.NewReader(os.Stdin)
	var n int
	fmt.Fscan(reader, &n)

	var s1, s2, s3, val int64

	for i := 0; i < n; i++ {
		fmt.Fscan(reader, &val)
		s1 += val
	}
	for i := 0; i < n-1; i++ {
		fmt.Fscan(reader, &val)
		s2 += val
	}
	for i := 0; i < n-2; i++ {
		fmt.Fscan(reader, &val)
		s3 += val
	}

	fmt.Println(s1 - s2)
	fmt.Println(s2 - s3)
}
