lol wtf.

But I guess I understand, this one is so mind numbingly hard that a video guide is a must

input: 79o0w

and use proper markdowns

JavaScript Completions 1516

Please, when reporting an error, provide the input, your function output and the expected output, so we can tell you if there is an error or it is a problem with your code.

Why is that? In which language? With only that, there is nothing we can do.

Please refrain of posting kata solutions on public places. From: https://github.com/Codewars/codewars.com/wiki/Community-Code-of-Conduct

Please do not post your solutions on Github. We realize you would like to use these challenges as your resume, but you should have side-projects for that. If a Code Warrior is unable to find a solution online, then they are further encouraged to complete the task themselves - which will enable them to get more value out of their time spent.

I think that applies to youtube or any other place too.
