For problem statement at 2000-2999/2100-2199/2140-2149/2148/problemA.txt this is a correct solution, but verifier at 2000-2999/2100-2199/2140-2149/2148/verifierA.go ends with reference failed on test 1 (single_even): runtime error: exit status 1
stat /home/ubuntu/codeforces/2000-2999/2100-2199/2140-2149/2148/2000-2999/2100-2199/2140-2149/2148/2148A.go: no such file or directory

input:

5 2
exit status 1 can you fix the verifier? package main

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

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

	var t int
	fmt.Fscan(in, &t)
	for i := 0; i < t; i++ {
		var x, n int64
		fmt.Fscan(in, &x, &n)
		if n%2 == 1 {
			fmt.Fprintln(out, x)
		} else {
			fmt.Fprintln(out, 0)
		}
	}
