 Need Help??
I had to spiral too.
```my \$n = shift;
my @AoA;

my \$flip = 0;
my @directions = ( 'right', 'down', 'left', 'up');
my \$direction = \$directions[ \$flip % 4 ];
my (\$x, \$y) = (0, 0);

for ( 1 .. \$n * \$n ){
\$AoA[ \$x ][ \$y ] = \$_;

\$flip++ if 'right' eq \$direction and ( \$x == \$n - 1 or \$AoA[ \$x +
+1 ][ \$y ]);
\$flip++ if 'down'  eq \$direction and ( \$y == \$n - 1 or \$AoA[ \$x ][
+ \$y + 1 ]);
\$flip++ if 'left'  eq \$direction and ( \$x ==  0     or \$AoA[ \$x -
+1 ][ \$y ]);
\$flip++ if 'up'    eq \$direction and (                 \$AoA[ \$x ][
+ \$y - 1 ]);

\$direction = \$directions[ \$flip % 4 ];

\$x++ if 'right' eq \$direction;
\$y++ if 'down'  eq \$direction;
\$x-- if 'left'  eq \$direction;
\$y-- if 'up'    eq \$direction;
}

for my \$y (0..\$n-1){
for my \$x (0..\$n-1){
printf "%5d ",  \$AoA[\$x][\$y]; # for some value of 5
}
print "\n";
}
