Let's complete our own version of the classic Mario Bricks assignment from CS50!

Write a method named makeBricks that accepts a single int and returns a String containing a Mario pyramid of # characters. For example, given the input 4, that would look like this:

   #
  ##
 ###
####

You can find more examples and some hints here. The int passed to makeBricks will be positive. And note that your result should end with a newline character.
