You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 1493C_test.go
    path of file: ./repos/codeforces-go/main/1400-1499
    
    the code of the file until where you have to start completion: package main

import (
	. "fmt"
	"github.com/EndlessCheng/codeforces-go/main/testutil"
	"io"
	"testing"
)

// https://codeforces.com/problemset/problem/1493/C
// https://codeforces.com/problemset/status/1493/problem/C
func TestCF1493C(t *test
    
func TestCompareCF1493C(t *testing.T) {
	//return
	inputGenerator := func() string {
		//return ``
		rg := testutil.NewRandGenerator()
		rg.One()
		n := rg.Int(1, 6)
		rg.Int(1,n)
		rg.NewLine()
		rg.Str(n,n,'a','z')
		return rg.String()
	}

	// 暴力算法
	runBF := func(in io.Reader, out io.Writer) {
		var T, n, k int
		var s []byte

		for Fscan(in, &T); T > 0; T-- {
			Fscan(in, &n, &k, &s)
			if n%k > 0 {
				Fprintln(out, -1)
				continue
			}
			Fprintln(out, "")
		}
	}

	testutil.AssertEqualRunResultsInf(t, inputGenerator, runBF, CF1493C)
}
