2. 편집 지침

• 수록 순서를 변경하지 마십시오.
• 문서는 예제의 종류를 대분류로 하여, 프로그래밍 언어를 알파벳, 가나다 순으로 정렬하여 주십시오.
• 예제의 종류는 Hello, world!, 구구단, 삼각형 그리기, 99병의 맥주, 1부터 N까지 출력 순서를 유지하여 주십시오.
• 난해한 언어의 예제는 프로그래밍 언어/예제/난해한 프로그래밍 언어 문서에 추가해 주십시오.
• 이해하기 쉽고 간단한 코드 예제로 작성해 주십시오.
• 복잡한 연산이나 라이브러리를 사용하지 마십시오.
• 원라이너 등 코드의 가독성을 해칠 수 있는 예제를 수록하지 마십시오.
