You literally just need to look through all the test case to find out the patterns
Don't just brute force your way out of this

I found the bag For code weirdReverse=a=>a.sort(_=>-1) i got error weirdReverse([1,2,3,4,5])
Should return [5,4,3,2,1]
Array must be reversed - Expected: '[5, 4, 3, 2, 1]', instead got: '[1, 2, 3, 4, 5]',
but my code RETURNS right variant in my IDE.

And it's no use to flood the Discourse page for this.

timeout issue

My code is works nise but this shit gives timeout error. I fully changed the code 3 times.

For input string: "4726530891"
It's too much even for long type. rep-

I have exactly the same problem. I am using C#

Your answer is missing 'cab'

I got a problem. All test passed, but i can't confirm... expected [ 'abc', 'acb', 'bac', 'bca', 'cba' ] to deeply equal [ 'abc', 'acb', 'bac', 'bca', 'cab', 'cba' ]... wtf?
