Ok, fixed.
I checked that the simple tests pass, and that the full tests pass, and it is OK.
Still when I publish, thre is a orange messag at the bottom stating that I submitted with failing tests.
I don't understand the problem.

I made most of the changes you suggested, but I could not resolve the 4th point, changing the make_pair to initializers.
the reason is that Equals cannot resolve ty type from initialization list to properly typed pair.
Do you have a simple way to do it ? I think I probably overlooked something.

Thank you !
I will will make the modifications.

Success! thank you!

Same here, I cannot complete the kata in C++, very frustrating...
