개미 수열을 푸는 10가지 방법
개미 수열을 푸는 10가지 방법
알아두면 피와 살이 될 프로그래밍 개념 10가지
책 소개
이 책은 심심풀이로 시작되었다. 하지만 어쩌다보니 2년에 걸쳐 갖가지 방법이 동원되었다. 단지 '개미 수열' 한 문제를 풀기위해 정규표현식, 이터레이터, 코루틴, CSP 등 다양한 프로그래밍 개념까지 적용되었다. 각 개념들이 왜 필요한지, 어떻게 동작하는지 두루 살펴본다.
개미 수열은 누구나 한번쯤 풀어봤을 법한 쉬운 문제다. 과연 그럴까? 개미 수열은 '읽고 말하기 수열(look-and-say sequence)'이라고도 알려져 있으며, 줄마다 30% 정도씩 길이가 늘어난다고 증명되었다. 기하급수적으로 커지기 때문에 대충 해서는 100번째 줄을 출력하기도 어렵다. 반면 Haskell 같은 언어에서는 큰 문제가 되지 않는다. 그 차이를 파고들어 Java나 JavaScript에서도 100번째 줄 혹은 백만번째 줄을 출력할 수 있게 프로그램을 고쳐나간다.
쉬운 문제를 통해 오래되었지만 여전히 유효한 개념들(코루틴(1958), 제너레이터(1975), CPS(1975), CSP(1978) 등)을 맛볼 수 있는 좋은 기회를 제공해 줄 것이다.
