That’s strange, it’s taken me like 2 minutes to think of three methods of reversing a string, depending on what you want, space efficiency (use two moving pointers and operate in-place), simplicity (use a new array and a loop starting at the origin’s end), functional semantics (use map() and a bit of modulo math)… I’ve written a lot of software but I wouldn’t even consider myself a professional programmer. What happens to these people, do they get really nervous or do they really not know?
