Chrono79(1 kyu). Hello! Thanks for the answer, but ... The problem is that I have already checked the data sent to the function! They ALWAYS start with a NOT unique number, for example: [0, 1, 0] or [1, 0, 1]! Moreover, as you can see from my remark above - I passed 15/16 sub-tasks! How is this possible with such an error? Thus, your remark on the code is not appropriate =( . By the way, there is another problem with numbers, when you try to sum them up, it turns out that an array with a mass of ones is equal to an exorbitant number!
Perhaps there is another solution to this situation! DIDN'T COME TO YOU THAT THE FUNCTION HAS BEEN BROKEN RECENTLY? After the moment you went through it a month or a year ago or something? Have you tested this function today?

But at the expense of statistics ... I mean ... God, does it not work as I thought all this time ?? -_- I'll go ... I'll try to find explanations for these icons ... I hope this is not my interpretation error (((

----------------@few minutes after...@-----------------------------------------
89% of 4,775 (4,775 / 13,625 - could have given a rating in total).
13,625 of 39,367 (less than 50% completed the task).

No! It seems that I correctly understood these statistics icons (correct me if not)! My comment was of a different nature. It was a matter of psychological evaluation in the first place! Okay ... I'll explain my remarks on statistics in a different way!
According to my observations (although few of them have been done), the standard for passing assignments of the lowest category is 50-66% of the participants. And this task is lower, since only 13k out of 40k were completed! The second remark was addressed to the fact that out of 13,000 who passed the task, only 5,000 gave a positive assessment! I believe that most of those who did NOT put a rating were dissatisfied with the task! And so they did not waste their time to honor this assignment! Maybe I'm wrong, psychology is not an exact science, especially mine ... (=

Hello! I believe this task is deeply broken for a long time! =) I have passed all tests except one!! Try to check the human-passing statistics firstly, than go for the function's parameter as var arr basically with looping @@console.log(arr[i]);@@ You will see that parameters, have rarely in themselves the wrong conditions: arrays + simple numbers outside of the array! Also 2 inputs-tasks are partially broken (with the large number '1099511627776'). Because: 1) they always have the same numbers in both types of compare. 2) I can not see them in the second array, but they are there (some math with those numbers tells me itself). 3) they always ask to return 0, and large number 1099511627776, but its a fake solution, I believe! Both tasks have 1099511627776 as unique, then why I should return zero at one of them???
