Earning points
Each problem has a set of tests. Once you think your code is working correctly (and you've used the run button to test it yourself!) you can submit your program to the marking system for testing.
You can run the marker as many times as you want, but be careful about points (as explained below).
You will receive points only for passing all the tests for a problem. You can submit as many times as you want.
Each problem is worth 1 point. Once you pass all of the test cases for a particular problem, you will be awarded the point.
