For problem statement at 0-999/0-99/60-69/64/problemH.txt this is a correct solution, but verifier at 0-999/0-99/60-69/64/verifierH.go ends with All tests passed can you fix the verifier? package main

import (
	"bufio"
	"fmt"
	"os"

	"strconv"

type Participant struct {
	name  string
	score int

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

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

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

	sort.Slice(a, func(i, j int) bool {
