Autograder demo: Quitting grading early

Because the Python autograder runs test cases in sequential order, we provide the capability to stop grading early, e.g. if there is some later test case that depends on the successful result of an earlier one. This can be done implicitly in most checks by passing accuracy_critical=True, or by specifically calling feedback.finish().

For some number $x$ given as the variable x, compute $y=x^2$ and store this as y.

Finally, compute $z=\sqrt{y+1}$ and save this as z.

The setup code gives the following variables:

Your code snippet should define the following variables:
