EXAMPLE
The array begins:
...........
0 0 1 0 0 1 0 1 0 ...
1 0 1 0 0 1 0 1 0 ...
0 0 1 0 0 1 0 1 0 ...
1 0 1 0 0 1 0 1 0 ...
0 0 1 0 0 1 0 1 0 ...
1 0 1 0 0 1 0 1 0 ...
This is to be read from bottom to top and left to right.
The initial antidiagonals (starting in bottom left corner) are:
1,
0,0,
1,0,1,
0,0,1,0,
1,0,1,0,0,
0,0,1,0,0,1,
1,0,1,0,0,1,0,
0,0,1,0,0,1,0,1,
