Exactly what I thought right now. I am amazed about this solution!

Thanks, that's good to know

why?

Surely enough, this was (and would be, I guess) the only time I saw the best answer the exact same as my one. Weird but true.

I was pleasantly surprised to see that the solution I thought would be considered an inefficient "naive" approach seems to be a pretty popular one, since I seem to be unfamiliar with advanced string manipulation/creation in C++.
Mine is pretty much the same, just with some minor formatting differences

oh shit yeahhhhh cases... forgot about cases

Same as mine! Nice job!
