Binomial Golf

[tachyon]

The other day the topic of the binomial distribution came up. The binomial distribution is a part of probability theory and looks like this:

                            1
                          1   1
                        1   2   1
                      1   3   3   1
                    1   4   6   4   1
                  1   5   10  10  5   1
                1   6   15  20  15  6   1
              1   7   21  35  35  21  7   1
            1   8   28  56  70  56  28  8   1
          1   9   36  84  126 126 84  36  9   1

I thought writing a sub to generate this would be easy.....

So here is another hole. Rules:

(1) sub accepts one arg which corresponds to the number of levels to print;

(2) sub prints it out

(3) formating like this is OK

1
1 1
1 2 1
1 3 3 1      <- this is level 4
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1
1 7 21 35 35 21 7 1
1 8 28 56 70 56 28 8 1
1 9 36 84 126 126 84 36 9 1
1 10 45 120 210 252 210 120 45 10 1

(4) how about we use strict, just for something different

I have <70 chars, can you do better? I'll post mine in 2 days
