Ok

Your solution crashes for large numbers. Try running it with n=160000.

Can you help me?
I've got this message in output:
Fatal error in , line 0

Fatal JavaScript invalid size error 169220804

If you have execution timeout, then the solution does not pass, despite of returning correct answers.

See if this paragraph helps.

My solution passed tests, but Execution Timed Out (12000 ms). I used BigInt in the loop for big calculations. What should i do?

did not understand your hint and have used AI

Object.keys doesn't work on an iterable object ( well, it does, but it doesn't do what you want it to do ). You have to iterate it. Follow the link in the description and read up on the protocol.

This question was already answered here.

               v                           v   v
expected [ 9, +0, 9, 1, 2, 1, 1, 3, 1, 9, +0, +0, 9, +0, +0, +0, +0, +0, +0, +0 ] to deeply equal 
         [ 9, 9, 1, 2, 1, 1, 3, 1, 9, 9, +0, +0, +0, +0, +0, +0, +0, +0, +0, +0 ]

The first value there is your answer, and you can see there are more than one 0 not at the end. Probably you're mutating the array at the same time you run through it, skipping values.

About what +0 is, you can see that's 0, don't mind the + before it, it's probably chai adding it in the assertion.

I don't understand what is wrong
expected [ 9, +0, 9, 1, 2, 1, 1, 3, 1, 9, +0, +0, 9, +0, +0, +0, +0, +0, +0, +0 ] to deeply equal [ 9, 9, 1, 2, 1, 1, 3, 1, 9, 9, +0, +0, +0, +0, +0, +0, +0, +0, +0, +0 ]

+0 what is this?

I solve it with using integer->string conversions, then without using integer->string conversions. But everytime a have Execution Timed Out (12000 ms)

no, it returns with commas

But this solution return number without "," (commas)

Resolved.

Alright my thought process was incorrect. Thanks for the fast response you are 100 % correct. I did not realise i and j can be the same to solve this. That was my problem. Resolved.
