For problem statement at 0-999/500-599/590-599/592/problemB.txt this is a correct solution, but verifier at 0-999/500-599/590-599/592/verifierB.go ends with All tests passed can you fix the verifier? ```go
package main

import (
	"fmt"
)

func main() {
	var n int64
	if _, err := fmt.Scan(&n); err == nil {
		fmt.Print((n - 2) * (n - 2))
	}
}
```
