It was David Ward Lambert's idea to write a one line expression with the
fewest tokens. We worked together and got to 40 tokens. Any ideas to make
this any better.

Hopefully David will send his version of 39 tokens but not simple J. Note
also that you must paste the long line for wave together.

Part 1: Use viewmat and create a little flag. Next design a function to
rotate it clockwise 90 degrees successively until it is in the original
position.

Reshape A into a 9 9 square matrix. Justify all lines in the center. If a
line has an even number of letters put the extra letter on the left. Now
design a function to rotate the words in a similar fashion to the flag
above. Note the letters in "we" as they move around clockwise. Your
function should work for any square literal matrix.
Happy Memorial Day!
