Question : 787B - Not Afraid My solution : 99205991
My thought process:
We have to make sure that in every group at least one pair of Ricky & Morty of same Universe are present to prevent the destruction.
My Idea:
insert all the absolute value of members in each group to both a Set & a Vector. If the size of both of them are equal in any group would mean a possibility of destruction ("Yes") else No.
My apologies in advance if I am missing something obvious. Thank you for your time.
A person can join a group multiple times , if rick from the same universe joins a group twice , you might print no.
