똑똑한 코드 작성을 위한 실전 알고리즘
3.1
키와 연관된 값
값을 단순히 저장하는 대신에, 특정 키와 값을 연결하는 (키, 값 ) 쌍의 컬렉션을 저장할 필요
가 있다. 이는 주어진 키에 연관된 값을 찾도록 해주는
심볼 테이블
symbol
table
데이터 타입으로
알려져 있다. 해싱은 (키, 값 ) 쌍을 찾기 위해 처음부터 끝까지 수동으로 탐색하는 것보다 효
율적인 대안이 되며, 앞서 다룬 탐색 알고리즘들을 능가한다. 심볼 테이블은 키 (및 해당하는
값)를 제거하는 과정에도 효율적일 수 있다. 모든 키를 특정 순서로 (예를 들면 오름차순으로)
얻어오는 기능을 포기해야 하지만, 심볼 테이블의 결과는 개별 키와 연관된 값을 얻거나 저장
하는 데 최적의 성능을 제공한다.
특정 해의 특정 달에 해당하는 달력을 출력하는

는 다음과 같이 출력할 것이다.
