In many computer systems and networks, different users are granted different levels of access to different resources. In this case, you are given a int[] rights, indicating the privilege level of each user to use some system resource.

Constraints users will contain between 0 and 50 elements, inclusive. Each element of users will be between 0 and 100, inclusive. minPermission will be between 0 and 100, inclusive. Examples a)  {0,1,2,3,4,5} 2 Returns: "DDAAAA" Here, the first two users don't have sufficient privileges, but the remainder do. b)  {5,3,2,10,0} 20 Returns: "DDDDD" Unfortunately, nobody has sufficient access. c)  {}
