For problem statement at 1000-1999/1600-1699/1610-1619/1610/problemA.txt this is a correct solution, but verifier at 1000-1999/1600-1699/1610-1619/1610/verifierA.go ends with ok 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
	if _, err := fmt.Fscan(reader, &t); err != nil {
		return
	}

	for i := 0; i < t; i++ {
		var n, m int
		fmt.Fscan(reader, &n, &m)
		if n == 1 && m == 1 {
			fmt.Fprintln(writer, 0)
		} else if n == 1 || m == 1 {
			fmt.Fprintln(writer, 1)
		} else {
			fmt.Fprintln(writer, 2)
		}
	}
}
