In order for the answer to be [yes] then both statements for an individual must be true: They have no direct report and that they have 5 or more supervisors.

The first question: "Do they have a direct report?" can be determined by looking in the Supervisor Id list. If an employee's Id is listed in this column than they have a direct report. We can quickly determine that none of the 3 employees in question are listed. Therefore none of them have a direct report and therefore pass this first question.

The second question: "Do they have at least 5 supervisors in total". The question tells us that if A supervises B and B supervises C then A also supervises C. In which case C would have 2 supervisors.

ONeil(id=8) is supervised by 11 who is supervised by 4 who is supervised by 9 who is supervised by 1 who is supervised by 6 who is supervised by 14 who has no supervisor listed. I.E

Oneil:11->4->9->1->6->14 added together : 6 supervisors in total. Mark "Yes"

Patel(id=7): 3->1->6->14 added together: 4 Mark "No"
Schickler(id=2) 10->6->14 added together: 3 Mark "No"
