Your function generates an incorrect deck, that's why your solution is not passing. What the log says in this case is: your deck should contain the following elements (obviously not what your deck must be in order, since we don't care about that, unless you returned twice the same deck in order).

Nope, that one teaches a more in-depth concept

start <= n <= limit
m > n

Maybe I don't understand your post but the first fixed test in "ATTEMPT" is testing(310, 2755, [1050, 1925]) so where is the problem?

OK it is your point of view. Anyway it is too late for a change. Sorry!

resolved

Fixed an issue in the ref solution.

@jamad:
word: c, seq: ['d', 'nqk', 'n', 'gui', 'jzd', 'vsxk', 'q', 'hqvlf', 'lc', 'ep', 'pic', 'c', 'quav', 'aga', 'mmhb', 'gosvf', 'm', 'sroz', 'myeus', 'pifgp', 'v', 'vs', 's', 'wf', 'kxtd'], expected = True

It expects True. Also, your solution is timing out. When did you notice this?

Thanks for your posts!

Modified. Could you give it a try?

ok retry now please

the it block is using the array after it has been passed to the user. I bet it's a poblem about the user mutating the input, so the message isn't trustful anymore.

I haven't witnessed this behavior in Python. I ran 10,000 tests.
