Five if conditions correspond to five conditions respectively.

/* A group selects A number of views from the following areas: A, B, C, D, and E:
1) If you want to remove A, you must go to B;
2) D and E can only go to one location;
3) B and C can only go to one location;
4) C. D. Neither go nor go;
5) if you go to E, A and D will also go.
Where can the group go at most?
