만들어질 배열의 길이를 알 수 있는데 List를 사용할 필요가 있을까요

List를 배열로 만들기 위해 stream api를 거치는 것 보다 toArrray() 메서드를 이용하는게 좋을것 같습니다.
내부에서 mapToInt 내에서 아무 로직도 수행하지 않는데 굳이 필요 할까요?
만약 위에서 길이가 정해진 배열을 만들었다면 List를 배열로 다시 만들 필요가 없을 것 입니다.

클로저의 내부 변수는 외부에서 참조가 가능해지므로 가비지 컬렉션에 의해 사라지지 않아 함수의 실행 이후 지속적으로 참조가 가능합니다. 다만 자원을 점유하게 되는데요.
이 함수에는 내부변수가 없고 실행이후 지속적으로 참조할 필요가 없는데. 클로저로 작성한 이유가 있나요?

1-2 k번쨰 수 문제 풀이.
기존 체이닝 메서드 말고 한번 그냥 구현하는 방식으로 연습을 해보는 것도 필요할 것 같음.
