Random tests in Python can't generate arrays of different size, and the fixed test where the arrays have those sizes expects False.

I am getting the same result. I printed both array in the test and looks like that the test case is wrong. there are 9 numbers in array1 and 8 numbers in array2. so the result is false.

Your function is returning False when it should return True. Probably an edge case, maybe two empty lists. Print the input to figure it out.

what does mean Basic tests faild: 'False should equal True' ?
and 48 tests passed
