문제

상근이는 Sogang ACM-ICPC Team의 회장이다. 서강대학교 컴퓨터 학생들은 하나 또는 그 이상의 학회에 소속되어 있다. 상근이는 학생들이 어떤 학회에 소속되어 있는지 조사해보려고 한다.

상근이는 학회원의 정보를 다음과 같이 작성한다. 아래 예시는 sisobus와 weissblume은 icpc의 학회원이라는 뜻이다.

icpc:weissblume,sisobus.

콜론(:)의 앞에는 학회의 이름이 쓰여 있고, 뒤에는 학회원이 주어진다.

어떤 학회는 모든 회원이 다른 학회에 소속되어 있을 수도 잇다. 따라서, 학회원을 적는 곳에 학회의 이름을 적을 수도 있다.

slug:sisobus,minhyeok,icpc,exupery.

icpc에 소속되어 있는 사람은 slug에도 소속되어 있다는 뜻이다. 즉, slug의 학회원은 아래와 같다.

slug:sisobus,minhyeok,weissblume,sisobus,exupery.

이 경우에 sisobus는 두 번 등장한다. 중복되는 사람의 이름을 하나로 줄이게 되면, 아래와 같이 하나로 줄여서 작성할 수 있다.

slug:sisobus,minhyeok,weissblume,exupery.

학회의 회원 정보가 주어졌을 때, 각 학회의 학회원이 몇 명인지 구하는 프로그램을 작성하시오.

상근이가 작성하는 방법에는 학회의 이름이 중첩될 수도 있다. 아래 예시에서 one에 소속된 회원은 abckhw 한 명이다.

one:another.
another:yetanother.
yetanother:abckhw.

입력

입력은 여러 테스트 케이스로 이루어져 있다. 각 테스트 케이스의 첫째 줄에는 학회의 수 n이 주어진다. n은 100을 넘지 않는 양의 정수이다. 다음 n개 줄에는 각 학회의 학회원 정보가 문제에서 설명한 형식으로 주어진다. 콜론(:) 앞은 학회 이름이고, 그 뒤쪽은 회원의 이름이 콤마(,)로 구분되어져 있다. 각 정보의 마지막에는 마침표(.)가 하나 주어진다.

학회의 이름은 서로 다르다. 학회원 정보에서 주어지는 회원이 학회 이름이 아닌 경우에는 사람의 이름이다.

입력으로 주어지는 학회 정보에서 순환을 이루는 정보는 없다.

각 그룹 또는 사람의 이름은 비어있지 않은 문자열이며, 길이가 1과 15 사이이다. 또, 알파벳 소문자로만 이루어져 있다.

입력의 마지막 줄에는 0이 하나 주어진다.

출력

각 테스트 케이스에 대해서, 제일 처음으로 주어지는 학회에 포함되어 있는 회원의 수를 출력한다.
