괴팍한 과학자 원형파이는 괴팍한 메커니즘을 가진 실험 도구를 만들었다.
이 도구를 사용하기 위한 실험 재료는 백금, 금, 은이다.
괴팍한 과학자의 연구소에는 백금, 금, 은이 1g씩 분리되어 작은 캡슐에 담겨 있다.
각 종류별로 캡슐은 100개 이상 존재함이 보장된다.
처음에 세 종류의 캡슐을 총합 100개를 넣으면 도구가 알아서 작동된다.
도구는 캡슐이 단 한 개 남을 때까지 다음과 같은 일을 진행한다.
1. 모든 캡슐 중 무작위로 종류가 다른 두 캡슐을 뽑는다.
2. 두 캡슐은 뿅 사라지며, 두 캡슐 이외 종류의 캡슐이 뿅 생겨난다.
1에서는 이전 단계 중 2에서 생성된 캡슐을 뽑을 수 있다.
현재 괴팍한 실험도구에는 백금 캡슐이 49개, 금 캡슐이 29개, 은 캡슐이 21개 들어 있다.
작동 전에 마지막 한 캡슐을 넣으려고 한다.
실험 도구가 작동을 멈추었을 때, 괴팍한 과학자는 백금 캡슐이 남아있기를 원한다.
넣어야 할 마지막 캡슐과 그 이유를 대어라.
