Ah ok. Can you show me your code?

You can add some print-statements to the test yourself, like this:

      next 7 [1..10000] `shouldBe` (Just 8)
      print "passed test1"

That way the terminal will print a test is done when it has succeeded.
Good luck!

Theses tests test if function value gives correct results when provided as last argument. (Remember value argument may be a value or a function :
You may assume:

• at least 2 arguments (d1and value) are provided
• each d argument will be a positive integer
• value argument may be a number, a string, a boolean, ...

If value is a function then the result of this function will be attribued to the item.

)

In theses cases some values are expected in very first/last items of resulting array (1st item of 1st subarray, last item of last subarray), it seems your solution doesn't return expected values.

Hope it helps!
