Implement an access sharing scheme based on the cubic function y=x3+ 7x-+2ax+5 for a company with 5 VPs and 8 managers. This scheme requires one VP and two managers to grant access to a resource. Only VPs and managers are part of the scheme (no CEO and President). Every point should be used by a VP/manager only once (cannot be assigned to multiple employees). Show how this scheme is used to recover the coefficients for the following cases: 4th VP and (a (mod 8)+1 )th and ((a+1) (mod 8) + 1 )th managers. (25 pts)
