Do you really need to calculate factorial of numbers > 20! ?

"hob has to learn C++" is a secondary matter. in the first place, i have to know it's C++ because if I don't know this, which language should I learn? :D

I believe both of those doesn't know how "Show solution" button work. It can only show the solution of the user in the selected language (next to the name of the kata). So, hobovsky can't read the solution of the OP using the button because he hasn't done it in C++. It would make him has to learn C++ first, and then solving the kata. Meanwhile, the OP can just send their solution here with the spoiler flag (so that other people that haven't solved the kata can't read it) so that he can just start researching on the part of code that doesn't meet the criteria of the kata. The latter would be a faster way to get this kata fixed.

Oh come on, i will not forfeit a kata only to find a piece of information which OP can already provide with 0 effort. If I forfeited every kata i want to fix, i would have nothing left to solve.

To see your solution, I have to complete tha kata in the same language as you. And since I do not know your language... I would have to complete the kata in three languages to see your solution. And I know only one of them. So I have to solve the kata in two languages which I do not even know to see your solution. I wold have to use a lot of google and a lot of reading to solve it. The kata is 5 kyu, which means not easy. I would have to solve a non-trivial kata in three languages, including two languages which I do not know.

But the "unlock solutions" button exists. The whole paragraph is incorrect. Although I agree that the OP could be nicer and at least mention the language from the start.

Dear Hobovsky, Seems as before you had read my comment a bit too literally.

Oh this is possible, I read so many comments I can't keep track anymore which are serious and which are not :)

Actually, if you were interested to identify the language of tests which pass or not pass you might simply pass the kata, and thereafter look at my only solution.

This, unfortunately, does not work this way. To see your solution, I have to complete tha kata in the same language as you. And since I do not know your language... I would have to complete the kata in three languages to see your solution. And I know only one of them. So I have to solve the kata in two languages which I do not even know to see your solution. I wold have to use a lot of google and a lot of reading to solve it. The kata is 5 kyu, which means not easy. I would have to solve a non-trivial kata in three languages, including two languages which I do not know. On your end, however, all it takes is to paste your solution in code blocks, put a spoiler flag, and voila! done. Knowing your language, and using your solution for reference, I can start searching for the bug and fix it.

You marked the post as ISSUE. Issues mean kata bugs, and bugs need to be fixed. I want to fix the bug. But I cannot fix it, because to even start fixing it I need to solve a not easy kata in three languages (two of which I do not know). If you want the kata to be fixed, help me to fix it. If you do not want the kata to be fixed, do not use the ISSUE label.

Thank you for your bug report, now I know literally nothing what would help me to fix the tests:

• I do not know the language of tests which pass (or fail) but should not,
• I do not know what is your solution, or any other solution which passes (or fails) tests but should not,
• I do not know what is the input of the test which passes (or fails) but should not.

Make your post useful! Share some details about the error so I can fix it! :D

Thre is no such thing as "included by deafault". If you use it, you need to include it. Otherwise you risk thing breaking in the future.
