For problem statement at 2000-2999/2000-2099/2090-2099/2091/problemC.txt this is a correct solution, but verifier at 2000-2999/2000-2099/2090-2099/2091/verifierC.go ends with All 85 tests passed can you fix the verifier? package main

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

func main() {
	reader := bufio.NewReader(os.Stdin)
	writer := bufio.NewWriter(os.Stdout)
	defer writer.Flush()

	var t int
	fmt.Fscan(reader, &t)

	for i := 0; i < t; i++ {
		var n int
		fmt.Fscan(reader, &n)

		if n%2 == 0 {
			fmt.Fprintln(writer, "-1")
		} else {
			for j := 0; j < n; j++ {
				if j > 0 {
					fmt.Fprint(writer, " ")
				}
				fmt.Fprint(writer, (2*j)%n+1)
			}
			fmt.Fprintln(writer)
		}
	}
