All points except for one lie on a line. Which one is the outlier?
Example:
You are given a list of x-y pairs in a column like this:
pts = [ 0 1
0 2
3 2
0 3
0 4 ]
You would return the number 3, since the third point is the only one that is non-collinear with the other points. All the others are on the y-axis.
outlier = 3

The instructions were a bit confusing at first. It would have been better to say "Find the row number of the outlying point."
Also, using the third row as an answer and a 3 in a column of zeros makes it seem like the intent was to provide unclear instructions. (Or they are just used to writing college textbooks ;) )
The test set cases 2,3 seems to have two outliers for each case. Please check it
i struggled with this one, not so much because of the concepts/maths involved, but because of issues with floating point precision that occur with test case 3 where my functions kept erroring after determining that 15.0000 ~= 15
