Magic numbers. Not Chando's numbers. Wonder where the author got Chando's numbers from. Google doesn't seem to think they exist. Great kata though.

Nice kata. Sad to see author myjinxin2015 has been mia for 3 years.

Ah! just what I was wondering. Thanks for answering. The description should state this.

Difficult! At this time not willing to spend the time to figure it out. Moving on to other katas but maybe return to this kata some day.

So the extra white spaces are not just after the commas but can also be part of the user ids in which case should not be removed. That should have been clearly stated in the description.

Misleading. Its not just words, it's words separated by spaces, then the comma. And some of the words are less than n in length.

Nice kata but should have logic and/or puzzle tag.

I dont know what to change it to. You need help from an admin to fix the problem. Request admin help and raise as issue.

Okay. Thanks. Was just doing that.

JavaScript here. What the heck is a linked list? And when he says method does he mean prototype? So it would be like Array.prototype.length = function (array){
return this.length;
}
?? Im real weak in this area, any explanation would be appreciated.

Yes.

Misleading description. No BigInt is mentioned. I made a kata and was told to make sure the description informed of the use of BigInt. You have to click on "Train" on this kata before you're informed of the BigInt. That turns this kata into a puzzle. Was just looking for a reasonable 7 kyu.

Nice kata. And perfectly graded as 7 kyu.

Strange that there is a line break at the end of the string where it is not needed.

My advice for those people having timeout problems is to google "isPrime function" for your language. If you see a square root method as a for loop parameter, that is best. No need for nested loops. Nice Kata.
