Write a program named PlusSigns.java that asks the user for a number from 1-10 and then prints an inverted "triangle of plus signs".

For example, an input of 6 would produce this output:

+++++++++++

  +++++++++  

    +++++++   

      +++++    

        +++     

         +

Hint: Make a table that tells how many leading spaces and plus signs you'll need:

                     row   #plus signs   #spaces

+++++++++++      0       11           0

 +++++++++        1        9           1  

  +++++++           2        7           2   

   +++++             3        5           3    

     +++              4        3           4    

      +                 5        1           5

Then use that to figure out formulas that, given a row number, will tell you how many spaces and plus signs you need to print in the inner loop.
