I give you ascii-art, you make it pseudo-3d Do you know the optical effect of a tridimensional hand painted whit horizontal lines?
Examples
This challenge consists of making something like that effect with ascii, and transforming one 2d input into a &quot;3d&quot; output.
The algorithm
To perform this transformation, you first replace all 1 with a ¯ and all 0 with a _. In order to make things more realistic, you should replace a ¯ that does not have another ¯ before it with /, and a ¯ that does not have another ¯ after it with \.
Some examples:
Input:
001111100

Output:
__/¯¯¯\__

Input:
0110
1111

Output:
_/\_
/¯¯\

^ In this case, there are multiple lines, so apply this to all lines.

Exceptions / rules:

The input will never have a single positive cell in a row (e.g. 00100)

You can consider other characters for the input. However, it should only be two characters and not the same characters that the output uses. For instance:


Valid input:    0001111000 # two characters, different from the output
Valid input:    aaiiaiiaaa # two characters, different from the output
Valid input:    ,€€€€,,,,, # two characters, different from the output
Invalid input:  0001223000 # four different characters are used.
Invalid input:  ___1111___ # invalid, because the output uses underscores.
Invalid input:  ///\\\\/// # both slash and backslash are used by the output.


The output must use the four characters described above and only those four. Alternatively, you may use - instead of the macron (¯)

The macron (upper character) has a codepoint of 175, but you may count it as one byte.


This is code-golf, so the shortest code in bytes wins.

26 bytes, but scoring ¯ as 1, as per note in challenge.
