REDUCE

LAMBDA를 각 값에 적용하고 누적기에 합계 값을 반환하여 배열을 누적된 값으로 줄입니다.

구문 REDUCE 함수 구문에는 다음과 같은 인수와 매개 변수가 있습니다. initial_value 누적기의 시작 값을 설정합니다. array 줄일 배열. lambda 배열을 줄이기 위해 호출되는 LAMBDA. LAMBDA는 2개의 매개 변수를 취합니다. accumulator 합산되어 최종 결과로 반환되는 값. value 배열의 각 요소에 적용된 계산. 팁 이 함수를 사용하기 전에 allowDynamicArray 옵션을 켜야 합니다. 기본 용도 제곱 값 합산 짝수 값만 계산
