I did the same thing with a switch, I like how he extruded the comparator to its own function. I didn't even think to just use a char array for memory then convert back to a string with the return line. I used a string array. (I also haven't coded in years xD) Very elegant!

I did this but added strings to a knew string. This is more efficient

I knew there would be a way to do this with replaces, clever
