老师出了一道题，只能写到这样，总是有错误，求大神指导
A、B、C、D、E、F、G、H、I、J 共10名学生有可能参加本次计算机竞赛，也可能不参加。因为某种原因，他们是否参赛受到下列条件的约束：1. 如果A参加，B也参加；
2. 如果C不参加，D也不参加；
3. A和C中只能有一个人参加；
4. B和D中有且仅有一个人参加；
5. D、E、F、G、H 中至少有2人参加；
6. C和G或者都参加，或者都不参加；
7. C、E、G、I中至多只能2人参加
8. 如果E参加，那么F和G也都参加。
9. 如果F参加，G、H就不能参加
10. 如果I、J都不参加，H必须参加
请编程根据这些条件判断这10名同学中参赛者名单。如果有多种可能，则输出所有的可能情况。
