1. 문제 이해
구현/시뮬레이션 문제입니다
2. 문제 해석
어항을 정리하는 매커니즘에 대한 감을 한 번 잡으면 구현 자체는 크게 어렵지 않은 문제입니다.
N도 4의 배수로 주어져서 예외 처리 해야 할 테케도 거의 없습니다.

}4. 코드 해설
- board를 new int[n][25]로 선언한 이유:
- new int[25][n]으로 선언하면 바닥(24, 0)부터 쌓아올려야 하기 때문에 index 관리가 어려울 것 같아서 0부터 index를 시작할 수 있도록 위와 같이 board를 선언했습니다.
- n이 최대 100임으로 아무리 접어도 쌓은 높이가 25를 넘을 수는 없습니다
- firstFold() 함수
코드와 아래 그림을 함께 보시면 이해가 편하시리라 생각됩니다.
핵심은 화살표 순서에 맞춰서 인덱스를 짜주는 것입니다. 이런 문제의 경우 보통 한 예제에 대해서만 이를 잘 지켜서 코드를 짜면, 예외 케이스가 없는 문제여서 다른 예제에서도 모두 잘 동작합니다.
