풀이 시작 : 2023-09-11 14:20

제한 조건

  • 주어지는 식의 길이는 최대 50

풀이 방법

  • 연산자는 '+' 아니면 '-'
  • 맨 앞에 -가 오는 경우는 없으므로 여는 괄호는 연산자 뒤, 닫는 괄호는 다음 연산자 앞에 올 수 있음
  • 최소 값을 만들기 위해 '-' 다음에 오는 구간을 최대로 만들어줘야 함
    • '-'연산자 뒤에 괄호를 열고 다음 '-'가 나오기 전에 괄호를 닫으면 '-' 구간을 최대로 묶을 수 있음
    • 55-50+40-10+20+30+40 -> 55-(50+40)-(10+20+30+40)
      풀이 완료 : 2023-09-11 14:58 (풀이 시간 : 38분)

전체 수식에 실제 bracket을 넣어서 식을 만드신 후에 eval을 통해 연산 결과를 확인해주시는 내용들이 시뮬레이션과 같다고 느껴져서 대단하다고 느꼈습니다. 고생하셨습니다!

저도 맨 처음 문제 풀 때 eval을 사용해서 풀었던 기억이 있는데..🙃
지수님 풀이 방식도 직관적으로 이해가 갔어요! 고생하셨습니다👍👍 나중에 코테에 얼마든지 비슷한 구현 문제가 나올 수 있을 것 같아요!

eval 함수로 날먹(?)하는 문제를 지수님과 함께 풀었던 기억이 있는데 저는 떠올리지 못했네요 ㅋㅋㅋ
직관적으로 문제에서 주어진대로 잘 풀어내신 것 같습니다!
리마인드 시켜주셔서 감사합니다 지수님!

직관적으로 문제에서 주어진대로 잘 풀어내신 것 같습니다!

리마인드 시켜주셔서 감사합니다 지수님!

전체 수식에 실제 bracket을 넣어서 식을 만드신 후에 eval을 통해 연산 결과를 확인해주시는 내용들이 시뮬레이션과 같다고 느껴져서 대단하다고 느꼈습니다. 고생하셨습니다!
