Answer 1

If it's urgent you should have started doing your homework earlier.

Answer 2

People are much more likely to look at your code if you put it in a script on sololearn playground.

Go to Code section, click +, select the programming language, insert your code, save.
Come back to this thread, click +, Insert Code, sort for My Code Bits, select your code.
