Answer 1

I've tried to find the stupid bug and here is the finding:
Logic seems okay, but there are some invisible invalid characters which are causing errors. Erase the spaces or rewrite the codes. You can see the error logs from here:

@Shamima Yasmin is right... And you can also easily see highlighted invalid spaces by copy/pasting it in code playground and open it with internet browser ;)
