Given an n-dimensional array M, find the size of M along the k-th dimension (1 <= k <= n), without using size(), height() or width(). You may ignore trailing singleton dimensions.

The test cases use undefined variables.
@Tim, everything is set before the first test case runs.
Interesting. We can't see anything before the first test, but it's there. For example, I couldn't test my code by pasting the tests into the scratch window, but I could submit and run it successfully. I've thought that CP 2166 is unsolvable because of missing code, but maybe it's just not visible.
@Chris, it's a quirk of Cody I recently discovered: if you submit a problem, all code in the test suite before the first section marker is run before the test suite but not shown as part of the test code. I used this feature (if it is indeed one) here partly in order to try it out, and partly in order to make cheating just a little bit harder.
If the consensus is that this hinders legitimate solutions, I can of course edit the problem to make the hidden code visible.
