For problem statement at 0-999/700-799/710-719/717/problemC.txt this is a correct solution, but verifier at 0-999/700-799/710-719/717/verifierC.go ends with All tests passed can you fix the verifier? package main

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

const MOD = 10007

func main() {
	in := bufio.NewReaderSize(os.Stdin, 1<<20)

	var n int
	fmt.Fscan(in, &n)

	a := make([]int, n)
	for i := 0; i < n; i++ {
		fmt.Fscan(in, &a[i])
	}

	sort.Ints(a)

	var ans int
	for i := 0; i < n; i++ {
		ans = (ans + (a[i]%MOD)*(a[n-1-i]%MOD)) % MOD
	}

	fmt.Println(ans)
}
