每个程序员都知道方括号[]{}()<>真的很有趣。为了加剧这种乐趣，可以将一组交织在一起的括号转换成可爱而模糊的图表。

假设您有一个包含方括号的字符串，例如[{][<(]})>(())。第一步是将琴弦顺时针旋转45度。（在Mathematica中，几乎可以使用来完成Rotate[ur_string,-pi/4]）。这是第一步的结果：

[
 {
  ]
   [
    <
     (
      ]
       }
        )
         >
          (
           (
            )
             )

接下来，在每个字符之间添加一个对角线空间。

[

  {

    ]

      [

        <

          (

            ]

              }

                )

                  >

                    (

                      (

                        )

                          )

接下来，从最左边的括号开始，并在其与犯罪伙伴之间画一个正方形。

+---+
|   |
| { |
|   |
+---+

      [

        <

          (

            ]

              }

                )

                  >

                    (

                      (

                        )

                          )

在每对括号中重复此过程，+如果需要，用s 覆盖以前的字符。

+---+
|   |
| +-+---------+
| | |         |
+-+-+         |
  |           |
  |   [       |
  |           |
  |     <     |
  |           |
  |       (   |
  |           |
  |         ] |
  |           |
  +-----------+

                )

                  >

                    (

                      (

                        )

                          )

继续进行，直到一切变得美好而方形。

+---+
|   |
| +-+---------+
| | |         |
+-+-+         |
  |           |
  |   +-----+ |
  |   |     | |
  |   | +---+-+---+
  |   | |   | |   |
  |   | | +-+-+-+ |
  |   | | | | | | |
  |   +-+-+-+ | | |
  |     | |   | | |
  +-----+-+---+ | |
        | |     | |
        | +-----+ |
        |         |
        +---------+

                    +-----+
                    |     |
                    | +-+ |
                    | | | |
                    | +-+ |
                    |     |
                    +-----+

输入项

输入内容应为单行的方括号，不要包含其他字符，每个方括号均是[]{}()<>。每种类型的托槽都是单独平衡的，尽管不同类型的托槽可能会重叠（这使正方形看起来很有趣）。尾随换行符是可选的。

输出量

输出将是从括号字符串生成的互锁方形图案。尾随空格和尾随换行符是可选的，但不得有前导空格。
