"faster" is true; "more effective" depends on the desired effect. Depending on your stdout, the behavior of the two is different, since endl forces a buffer flush.

You could hardcode with hash maps?

Can you explain how the lack of random tests is a problem here?

Added random tests in C# translation.

Understood. I tried to submit a set equality solution and got ornery. The accepted solutions are pretty good though admittedly.

No random tests in C++ and C#.

Thanks :)

Admittedly, the title is misleading. Unfortunately, as far as I know, it cannot be changed. Nevertheless the description is explicit and leaves no doubt about = being forbidden.

The name is pretty terrible and misleading. Why not just scan for two adjacent '='s? Why does any assignment result in an invalid solution? It's not an "==", it's a singular '='.

C Translation kumited.

nice kata!
