## Description
|
||
<section id="description"> “zig-zag”数组是第一个$ N ^ 2 $整数的正方形排列，当数组沿着数组的<a href="https://en.wiktionary.org/wiki/antidiagonal">反对角线</a>曲折时，数字会逐渐增加。例如，给定“'5”'，产生这个数组： <pre> 0 1 5 6 14
|
||
2 4 7 13 15
|
||
3 8 12 16 21
|
||
9 11 17 20 22
|
||
10 18 19 23 24
|
||
</pre>编写一个采用Z字形矩阵大小的函数，并将相应的矩阵作为二维数组返回。 </section>
