I fixed the test. There was no assert statement.
Needs more test cases
The test is wrong, the right answer is y_correct = [2 1 3 2];
solution is incorrect
Not really, we need to determine the first non-zero element in each column, not row.
The problem is pretty stupid, if there's only one test case. Then you can just return the correct result for this test case, without really computing anything (which is what the "best" solution to this problem does.
the best answer ! thanks
It looks like I forgot to put in size(x,2) instead of 4. Apparently the test suite didn't check that.
yup, definitely an issue...
