Algorithm::SpiralMatrix

Various Raku Sequences for spirals in matrix (two-dimensional arrays).

For overview see docs/test-output.md and docs/distance-variants.md.

Synopsis

use Algorithm::SpiralMatrix;

my $i = 1;
for square_distance(order => 'clockwise') -> ($x,$y) {
    say "{$i++} $x,$y";
    last if $i > 25;
}

will print

1 0,0
2 0,-1
3 1,0
4 0,1
5 -1,0
6 1,-1
8 -1,1
9 -1,-1
...
24 -2,2
25 -2,-2
