I have the same problem

Try to post your code (betwween two lines of three backticks, so that it is readable. If you don't know how to do that, Google "markdown"). Don't forget to mark your post as "Spoiler". If I have time I will look at it.

Same [unsupported type] errors here.

I tried a few C++ solutions (mine and those of guys who passed) and all worked fine. I don't know what happens to your code.
