I tried everything suggested in the discussion.
Each test works, but when I submit, I get WA2.

Can you please add more tests?

Strange ... and now I got AC without any change to the logic.
Just made each char taken from getchar() processed immediately instead of filling an array and then processing the array.
Both versions work equally well on my computer. I use VS 2022.

And one more thing -
absolutely the same way of reading the input and filling the array I initially had a WA2 with, worked perfectly for problem 1601. AntiCAPS. (Actually that's where I copied the functionality from before I start).

I guess Admins should take a look at this.
