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.

hmmm maybe i just did something wrong.... my code definitly worked in xcode and returned pairs, just not in code wars lol

I'm afraid your reading of the description was a bit too fast: 101-107 is not a 6-gap because there is 103 in between. This problem was already posted and you can see it below.

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.

i get a
Expected: equal to [unsupported type]
Actual: [unsupported type]
when using c++ but i was able to change my code for python and was able to pass it in
for c++ i am 100% sure used std::pair

i tried running it and it still shows me the same error

i get the same error too :(
