기본으로 제공된 예외 테스트에서
예외 테스트 -> 음수 테스트로 변경해주셔서 어떤 테스트인지 더 잘 보이게 된 거 같아요

지금은 preprocess여서 이전에 무슨 처리를 하는 거구나 인식은 되지만, 정확히 어떤 처리인지는 잘 모르겠어요.
그래서 sanitizeInput 같은 걸로 바꿔봐도 좋을 거 같아용

function num_check(value) {
const VALUE = Number(value);
if (isNaN(VALUE)) {
throw new Error("[ERROR] 숫자만 더할 수 있어요.");
}
if (VALUE < 0) {
throw new Error("[ERROR] 양수만 더할 수 있어요.");
}
return VALUE;
}이렇게 if문을 따로 둘 수도 있을 거 같아용
