给定以下参数，编写按字节数测量的最短代码以生成由菱形组成的ASCII网格：

• m-一行中完整菱形的数量
• n-行数
• s-最小菱形的一面
• r-嵌套级别-“基本的”内部有多少个菱形（在网格的相交点之间喜欢）

这利用了菱形的底部是顶部倒置（[::-1]）的事实，反复遍历range(n*2)并~x%2*2-1用于控制菱形的底部是顶部还是底部。
对于顶部（和底部），右侧仅是左侧，并替换/为\->l.replace(*'/\\')..[::-1]
要生成模式/嵌套，~-s*' '+'/'*(1+r*2)+~-s*' '将使用该字符串 /// 来进行迭代和切碎：

:R+          save the last number in variable R, then add the last 2 numbers (s+r)
,_           make an array [0 1 … s+r-1] and duplicate it
ff{…}        make a matrix, calculating for each (x,y) pair from the 2 arrays:
  -z         abs(x-y)
  R>         compared with R (1 if greater, 0 if not)
{…}%         transform each row of the matrix:
  _W%        duplicate and reverse it
  :~         bitwise-NOT each element (0 → -1, 1 → -2)
  \+         prepend to the original row
  "\ /"f=    replace numbers with characters from this string (by index):
              0 → '\'; 1, -2 → ' '; -1 → '/'
              this generates the "/\" part
_W%          duplicate the matrix and reverse the rows
Wf%+         reverse each row, then append (by rows) to the original matrix
