For problem statement at 1000-1999/1300-1399/1370-1379/1370/problemC.txt this is a correct solution, but verifier at 1000-1999/1300-1399/1370-1379/1370/verifierC.go ends with All tests passed can you fix the verifier? package main

	for i := int64(3); i*i <= x; i += 2 {
		if x%i == 0 {
			return false
		}
	}
	return true
}

	return x > 0 && (x&(x-1)) == 0
