Full program only--insofar as supporting the input requirements is concerned. Jelly implicitly Python evals the arguments to every program, so slash-separated input of two numbers becomes a float.

```
50R              For every [1 .. 50],
   >             is it strictly greater than
    ×ɗ           50 times the ratio?
      ị⁾-|       Replace 0 with | and 1 with -,
          Ø[j    and surround with [].
```
