Thank you! I got used to the fact that the minimum and maximum numbers are in the array itself. I should have read the condition more carefully.
Thanks again!

The instructions say: "You are given an array containing all integers from 1 to N, except one that is missing."
In this exemple, N=6 (it is the size of the input array) so the missing number is indeed 6.

Third test in attempt - [2,3,1,3,4,5] "pending" [6,3] ???
How can that be? Where does 6 come from?

Your solution returns wrong answer for strings like "1 2 3".

Your solution has a bug, it's not a kata issue.

11 should equal 'NaN'
123 should equal 'NaN'
there is assertion errors for python

Your kata has already been sent back to draft, closing...

CS:

• No random tests

• mocha + chai should be used

• Test.expect should be aborted

JS:

• No random tests

• mocha + chai should be used

• Test.expect should be aborted

No random tests in Ruby

Yeah, those were my thoughts exactly.
