Removed svm()

I'll remove the svm() however the feel of the puzzle was to get people to think out of the box.
When I have time I'll be making more riddles into code

I wouldn't say this is an issue.
Most people do the questions in Visual studio (or atleast I do, and it's a pet peeve of mine to add the static void Main(){} to every question.

Running the test cases were filled with errors.
Submitting worked.

Test Cases don't seem to be working

Maybe rename the method, it had a few of us giggling a bit.

Ideally yes, however as this is a real world example, you need to apply real world logic.

However I would suggest Randomised tests.

Neither n nor m can ever be less than 0 in your scenario
"You know that there are 'n' classmates and the paperwork has 'm' pages."

Whoops, fixing now.

Whilst this did work,

I made mistakes in the test cases, so this got through based on a loophole in the test logic.

Issues with TestCase naming.

Change the second "TestCase2" to "TestCase3"

Or consider a different naming convention.
