Nah man its cool everyone makes mistakes, I didnt want to sound judgemental it just puzzled me. Still though its not wrong, its working, just excess code.

Why make b = "true" and then return "true"? What's the point of making b = "true" if you're returning "true" either way. You could've just returned "true" without changing the value of b, or return b after b = "true". Same thing with false
