For problem statement at 0-999/100-199/170-179/171/problemC.txt this is a correct solution, but verifier at 0-999/100-199/170-179/171/verifierC.go ends with test 1 failed: expected "0" got "1"
exit status 1 can you fix the verifier? ```go
package main

import "fmt"

func main() {
	var a0, a1 int
	fmt.Scan(&a0, &a1)
	fmt.Println(2*a1 + 1)
}
```
