thanks people, my bad lol.

Please, before posting an issue look at the top of the page to see how many guys passed the kata. If this is big enough chances are that yor code is wrong. Cheers.

Please read description carefully: "Regardless of the order"

Alright, if doing your work in C++, absolutely take care what variable types you use, even in the function arguments. It seems like the row number variable can be extremely big, so the big test will fail if you use the wrong variable type!

Happened to me too. Nothing I've tried can fix this.

Holy shit this is dumb af. I could have just appended n at the end of my integers to convert them to BigInt. Please see lichuan's answer
