The correct issue: does not report actual and expected results in sample tests!

Brain fart on my end. I initially wrote the tester and used const int for the index n to ensure it wouldn't be modified within the scope of the tester. I carried over that same approach to the function definition, but you're right — since n is passed by value and not by reference, making it const doesn't serve any purpose in the function prototype.

I've corrected the prototype based on your suggestion!

Fixed.

It may have been about incorrectly written random tests. I have fixed it. Please check the incorrect solutions that passed the tests

follows is pretty simple
put the 1 at the end

Should be fixed.

duplicate report

The description states:

if the bit is 1, swap the case; if its 0, leave it as is.

And:

When you finish with the last bit of n, start again with the first bit.

What is inconsistent here?
