You could have taken a look at the sample tests. Also, weren't the error messages not clear enough about what the expected value was?

The input output example says:

• [4,6,2,1,9,63,-134,566] -> max = 566, min = -134
• [-52, 56, 30, 29, -54, 0, -110] -> min = -110, max = 56
• [42, 54, 65, 87, 0] -> min = 0, max = 87
• [5] -> min = 5, max = 5

I tried to replicate the exampled Output, a string saying "max = 566, min = -134", but all it actually wanted was the two values. I had to look into the solutions to get it right, because I had no idea what the task wanted for output.

I do not understand your problem. Your solution passes tests? IS there anything wrong with the kata? What do I need to fix?

I tried to replicate the output in the instructions as a string, but thats not the expected output? Come on...
