For problem statement at 1000-1999/1300-1399/1300-1309/1305/problemB.txt this is a correct solution, but verifier at 1000-1999/1300-1399/1300-1309/1305/verifierB.go ends with case 2 failed: expected "1\n12\n5 6 7 9 10 12 16 17 18 20 23 28" got "1\n12\n5 28 6 23 7 20 9 18 10 17 12 16"

exit status 1 can you fix the verifier? ```go
package main

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

func main() {
	in := bufio.NewReader(os.Stdin)
	var s string
	fmt.Fscan(in, &s)

	b := []byte(s)
	var ops [][]int

	for {
		l, r := 0, len(b)-1
		var chosen []int

		for l < r {
			for l < len(b) && b[l] != '(' {
				l++
			}
			for r >= 0 && b[r] != ')' {
				r--
			}
			if l < r {
				chosen = append(chosen, l+1, r+1)
				l++
				r--
			}
		}

		if len(chosen) == 0 {
			break
		}

		marked := make([]bool, len(b))
		for _, idx := range chosen {
			marked[idx-1] = true
		}

		var nb []byte
		for i := 0; i < len(b); i++ {
			if !marked[i] {
				nb = append(nb, b[i])
			}
		}
		b = nb
		ops = append(ops, chosen)
	}

	out := bufio.NewWriter(os.Stdout)
	defer out.Flush()

	fmt.Fprintln(out, len(ops))
	for _, op := range ops {
		fmt.Fprintln(out, len(op))
		for i, v := range op {
			if i > 0 {
				fmt.Fprint(out, " ")
			}
			fmt.Fprint(out, v)

		fmt.Fprintln(out)
