수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
[창의 퍼즐] 다음 글에서의 마침표 갯수 세어보시오(완전 노가다 문제)

<기자님들께>
앞으로 제 문제는 수학동아에 절대 올리지 말아주세요!
(이런 거저먹는 문제를 올릴리도 없겠지만)
..
...
.....
.......
...........
.............
.................
.......................
마침표가 위와같이 소수개씩 찍혀있다.
ㄱ번째 줄에는 ㄱ번째 소수개만큼 마침표가 있다.
ㄱ번째줄까지의 마침표의 수는 몇개일까?
(1)ㄱ을이용해서 나타내보세요.
이게 어렵다면
(2)10000번째 줄까지의 마침표의 갯수의 합은?
둘중 하나만 풀어도 인정
대신 2번 할거면 풀이 필수(이유:프로그램돌리면 1분안에 답나오기 때문)

코딩하지말라고 옆에 딱 적어놨는데...
그럼 풀이과정에 C언어 코드 적어놓으세요
