Ruby script to generate a Bolles-style "Prioritizing Grid"

n = 5

def pad(x)

  return " "+x.to_s if x < 10

  return x

end

1.upto(n-1) {|i|

  (i+1).upto(n) {|j|

    print "#{pad(i)}, #{pad(j)}   "

  }

  print "\n"

}

Example output:

 1,  2    1,  3    1,  4    1,  5  

 2,  3    2,  4    2,  5  

 3,  4    3,  5
