Dati due numeri interi come input in un array, disegna un rettangolo, usando il primo numero intero come larghezza e il secondo come altezza.

Oppure, se la tua lingua lo supporta, i due numeri interi possono essere dati come input separati.

Supponiamo che la larghezza e l'altezza non siano mai inferiori a 3 e verranno sempre fornite.

Esempi di output:

[3, 3]

|-|
| |
|-|

[5, 8]

|---|
|   |
|   |
|   |
|   |
|   |

[10, 3]

Grazie @WeeingIfFirst e @LuisMendo per alcuni byte =)

function z=f(a,b);z(b,a)=' ';z([1,b],:)=45;z(:,[1,a])='|'

Questo è davvero semplice in Matlab: prima crea una matrice della dimensione desiderata, quindi indicizza la prima e l'ultima riga per inserire il -, e fai lo stesso con la prima e l'ultima colonna da inserire| .

Ad esempio, f(4,3)ritorna

Spiegazione

L'approccio è simile a quello utilizzato in questa altra risposta . Il codice crea una matrice numerica del modulo

3 2 2 2 3
1 0 0 0 1
1 0 0 0 1
1 0 0 0 1
1 0 0 0 1
1 0 0 0 1
1 0 0 0 1
3 2 2 2 3

e quindi i suoi valori vengono utilizzati come indici (a base 1, modulari) nella stringa '|-| 'per produrre il risultato desiderato.

'|-| '                % Push this string
      2:"     ]       % Do this twice
         i            % Take input
          q           % Subtract 1
           W          % 2 raised to that
            Q         % Add 1
             B        % Convert to binary
               E      % Multiply by 2
                !     % Transpose
                 +    % Add with broadcast
                  )   % Index (modular, 1-based) into the string

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.
