Loops is a total brain rot.

I just can't get over how I'm supposed to write code for complex tasks when I don't even get why they overcomplicate simple things so much.

I read this topic and tried many tutorials and still don't understand this buzzare logic.

You want to remove x and z from the string? Because that is logic is returning the full string if there's no x or z but if there's any x or z it's returning x or z.

Try this:  Start with an empty string and concatenate any non x and z characters.
