Zeichnen Sie bei zwei Ganzzahlen als Eingabe in einem Array ein Rechteck, wobei Sie die erste Ganzzahl als Breite und die zweite als Höhe verwenden.

Wenn Ihre Sprache dies unterstützt, können die beiden Ganzzahlen auch als separate Eingaben eingegeben werden.

Angenommen, die Breite und Höhe betragen niemals weniger als 3, und sie werden immer angegeben.

Beispielausgaben:

[3, 3]

|-|
| |
|-|

[5, 8]

|---|
|   |

Wie es funktioniert

,þ%,ỊḄị“-|| ”Y  Main link. Left argument: w. Right argument: h

,þ              Pair table; yield a 2D array of all pairs [i, j] such that
                1 ≤ i ≤ w and 1 ≤ j ≤ h.
   ,            Pair; yield [w, h].
  %             Take the remainder of the element-wise division of each [i, j]
                by [w, h]. This replaces the highest coordinates with zeroes.
    Ị           Insignificant; map 0 and 1 to 1, all other coordinates to 0.
     Ḅ          Unbinary; convert each pair from base 2 to integer.
                  [0, 0] -> 0 (area)
                  [0, 1] -> 1 (top or bottom edge)
                  [1, 0] -> 2 (left or right edge)
                  [1, 1] -> 3 (vertex)
       “-|| ”   Yield that string. Indices are 1-based and modular in Jelly, so the
                indices of the characters in this string are 1, 2, 3, and 0.
      ị         At-index; replace the integers by the correspoding characters.

PowerShell v3+, 55 bytes

param($a,$b)1..$b|%{"|$((' ','-')[$_-in1,$b]*($a-2))|"}

Takes input $a and $b. Loops from 1 to $b. Each iteration, we construct a single string. The middle is selected from an array of two single-length strings, then string-multiplied by $a-2, while it's surrounded by pipes. The resulting strings are left on the pipeline, and output via implicit Write-Output happens on program completion, with default newline separator.

Alternatively, also at 55 bytes

param($a,$b)1..$b|%{"|$((''+' -'[$_-in1,$b])*($a-2))|"}

This one came about because I was trying to golf the array selection in the middle by using a string instead. However, since [char] times [int] isn't defined, we lose out on the savings by needing to cast as a string with parens and ''+.

Both versions require v3 or newer for the -in operator.
