Each card begins with the shared part from Person.
Try the problem first. Open one hint at a time.
super.card() runs the parent version of the method from inside the child version.
The child cannot read name (it is private), but super.card() already contains it.
Count students and teachers in main while you read the lines.
Write your Java code, run it on the examples and submit it to hidden tests.
