For problem statement at 1000-1999/1200-1299/1240-1249/1248/problemA.txt this is a correct solution, but verifier at 1000-1999/1200-1299/1240-1249/1248/verifierA.go ends with All tests passed can you fix the verifier? package main

import (
	"fmt"
	"io"
	"os"
)

func main() {
	buf, _ := io.ReadAll(os.Stdin)
	pos := 0

	nextInt := func() int {
		for pos < len(buf) && buf[pos] <= ' ' {
			pos++
		}
		if pos >= len(buf) {
			return 0
		}
		res := 0
		for pos < len(buf) && buf[pos] > ' ' {
			res = res*10 + int(buf[pos]-'0')
			pos++
		}
		return res
	}
