For problem statement at 1000-1999/1000-1099/1000-1009/1002/problemD2.txt this is a correct solution, but verifier at 1000-1999/1000-1099/1000-1009/1002/verifierD2.go ends with target runtime error on test 1: runtime error: fork/exec /tmp/build-372140356/solution: permission denied

exit status 1 can you fix the verifier? package answer

type Qubit bool

func X(q Qubit) Qubit {
	return !q
}

func CNOT(control Qubit, target Qubit) Qubit {
	if control {
		return !target
	}
	return target
}

func Oracle(x []Qubit, y Qubit, b []int) {
	for i := 0; i < len(x) && i < len(b); i++ {
		if b[i] == 0 {
			x[i] = X(x[i])
		}
		y = CNOT(x[i], y)
		if b[i] == 0 {
			x[i] = X(x[i])
		}
	}
