When I click Test, I get failed test for symbols. I spent some time to figure this out and never did. But then I clicked submit and all tests passed 😂

Thanks for this kata — short but clever use of mathematical string manipulation. It was a fun way to mix array operations with numeric logic, and it offered a neat perspective on working with π digit transformations without getting lost in heavy math.

Lovely! :)

I swear the sample tests were scuffed when I solved earlier.

Anyway, assertion messages are lacking if you want an actual issue I spotted.

what is missing ?

Python new test framework required.

Python random tests go up to 101 rather than 100?

fixed (had to remove #[allow(unused)] from the reference solution to see the warnings). also removed the useless mut modifier on the function's parameter.

• removed using namespace std; from the initial code
• added #include <string> to the test suite

duplicate of this issue

Nothing is said about symbols in the task, what's the point of writing them at all?

Merged the fix.
