When I try and submit final answer it always give me a message like this:

For this array: [-59, -57, -55, -54, -51, -48, -45, -44, -43, -40, -39, -36, -33, -32, -30, -29, -27, -24, -21, -19, -18, -17, -14, -11, -8, -7]

It should work for random inputs too:
'-59,-57,-55,-54,-51,-48,-45--43,-40,-39,-36,-33,-32,-30,-29,-27,-24,-21,-19--17,-14,-11,-8,-7'
should equal
'-59,-57,-55,-54,-51,-48,-40,-39,-36,-33,-32,-30,-29,-27,-24,-21,-14,-11,-8,-7'

When it really shouldn't equal that, it seems to be looking for an answer where consecutive numbers are removed..
