II$)$ void spiral$($int w$)$; prints the numbers $1,2,$dots,$w^2$ in a "spiral" order $($compared with

the square shape from part I above$)$ on one line.

Examples:

void spiral$(2)$ prints:

$1,2,4,3$

Because

$612$

$c^{3}4$

void spiral$(5)$ prints:

$1,2,3,4,5,10,15,20,25,24,23,22,21,16,11,6,7,8,9,14,19,18,17,12,13$

Because:$|$

write this function in c$($with only the stdio.h header and without a $2$d array$)$
