Herausforderungsbeschreibung

In der Taximetrik ist ein Abstand zwischen zwei Punkten wie folgt definiert:

Betrachten Sie eine Matrix mit nur Nullen und Einsen:

Lassen Sie uns jede 1auf den Abstand zum nächsten Unterschied 1 in der Matrix abbilden (natürlich unter der Annahme, dass der Abstand zwischen zwei benachbarten Zeilen / Spalten gleich 1 ist):

Finden Sie für diese Herausforderung anhand einer Matrix die oben gezeigte Entfernungskarte.

Anmerkungen

Sie können Eingaben in jedem vernünftigen Format vornehmen
Abgesehen von 0und 1können Sie zwei verschiedene Werte auswählen
Sie können davon ausgehen, dass eine Matrix nicht leer ist (mindestens eine Zeile mit einer Länge größer oder gleich 1 enthält) und auch rechteckig ist
Sie können auch davon ausgehen, dass mindestens zwei Wahrheitswerte in der Matrix vorhanden sind (andernfalls ist die Ausgabe undefiniert).
Sie können ein vollständiges Programm oder eine Funktion schreiben
Anstatt eine neue Matrix zurückzugeben, können Sie eine vorhandene ändern
Das ist Code-Golf , also machen Sie Ihre Byteanzahl so niedrig wie möglich!

Können wir Eingaben als Ganzzahl (mit Angabe der Breite) und als flaches Array annehmen?

Probieren Sie es online! Oder überprüfen Sie alle Testfälle .

Erläuterung

Um Zwischenergebnisse zu sehen, kann das Einfügen hilfreich sein X# zwischen zwei beliebige Anweisungen einen Anzeigestapel einzufügen.

t      % Implicit input: matrix. Duplicate
t0*    % Duplicate and multiply by 0. Gives a matrix of zeros
&v     % Concatenate vertically to input matrix. This is needed
       % in case the input is a row vector, because in that case the
       % subsequent &f would give row vectors, not column vectors
&f     % Push two column vectors with the row and column indices of
       % nonzero elements
h      % Concatenate into a 2-column matrix. Each row gives the
       % coordinates of a nonzero entry in the input matrix
t      % Duplicate
1&ZP   % Taxicab distance between the two copies of the 2-column
       % matrix containing the coordinates. The diagonal contains
       % zeros (distance of each point to itself)
tg     % Duplicate, convert to logical (turn nonzeros into 1)
/      % Divide, element-wise. This leaves off-diagonal entries in
       % the distance matrix unchanged, and sets the diagonal to NaN
X<     % Minimum of each column. NaN values are ignored. The 
       % resulting vector contains the new values to be written in
       % the input matrix
y      % Duplicate from below: push input matrix again
f      % Linear indices of nonzero entries
(      % Assignment indexing: write specified values at specified
       % positions. Implicitly display

Probieren Sie es online!

Ich gehe davon aus, dass kein Mensch versuchen möchte, diesen Code so zu lesen Versuchen Sie es also online mit Kommentaren, aussagekräftigen Beschriftungen und besser lesbaren Ausgaben!

Eingabe: Zeichenfolge, die ein Array darstellt. Die Zeichenfolge muss bis 3 Zeichen vorgenommen werden: 0, |Zeilenumbrüche darstellen, und jede positive digit größer als eins (PDGTO). Ich benutze gerne 8. OP erlaubt Eingaben in jedem vernünftigen Format und ich glaube, dass dies geeignet ist. Die Zeichenfolge funktioniert nicht hat , um Format zu einer rechteckigen Anordnung , aber es wird davon ausgegangen werden, linksbündig , was auch immer es ist.

Ausgabe: Array von Werten der minimalen Taxi Abstand von jeder zeigt PDGTOauf seinen nächsten andere PDGTO.

Das zweite Ausgabeformat ist deutlich einfacher zu lesen, fügt dem Programm aber auch 7 Bytes hinzu und das ist Code-Golf . Es wäre möglich gewesen, am Ende zurückzugehen und alle nachfolgenden Nullen zu entfernen, anstatt die 0Werte einfach aufzufüllen , aber das hätte noch mehr Bytes hinzugefügt und wurde als inakzeptabler Kostenfaktor angesehen.

Hier ist der Text des nicht golfenen Codes mit Kommentaren, besseren Beschriftungen und klareren Ausgaben:
( Dies ist derselbe wie mit dem obigen Link.)

[ Minimal Taxi Cab Distance ]
[ Inspired by: /codegolf//q/138311 ]

[ INPUT:  String of 8 & 0 using a pipe | as a delineator for each row of the array                  ]
[ OUTPUT: String formatted as an array showing min taxi distance from each 8 to the nearest other 8 ]
[ Note:   Any single digit > 1 may be substituted for 8. I.E., it must be 2 <= i <= 9               ]

[ PROCESS:                                                                 ]
[ Store STDIN exactly as input and keep it around until the end            ]
[ Store 3 arrays: Input, X Positions, Y Positions                          ]
[ Store a count of how many elements are in Input                          ]
[ For each element in Input, create an array of minimal taxi cab distances ]
[ Find the minimum value greater than zero in that array and store it      ]
[ Pad with a space and, if it's the last element in the row, a line break  ]
[ Repeat for each element, storing the minimums each time                  ]
[ Concatenate all the results and output                                   ]

[ DATA                     LOCATION              REASON                    ]
[ Input                    Auctioneer School     Close to Cyclone          ]
[ Input w/o Delineator     Tom's Trims           Running out of options    ]
[ Elements in Input        Rounders Pub          Close to Joyless Park     ]
[ Iteration                Joyless Park          Close to The Underground  ]
[ X Positions              Trunkers              Close to Rob's Rest       ]
[ Y Positions              Sunny Skies Park      Close to Bird's Bench     ]
[ Element's X              Rob's Rest            Easy to remember          ]
[ Element's Y              Bird's Bench          Easy to remember          ]
[ Array of distances       Narrow Path Park      LIFO is OK for this       ]
[ Array of minimums        Heisenberg's          Close to KonKat's         ]

[ Note: We use the Input w/o Delineator to keep track of iteration             ]
[ By storing it at Chop Suey, we can keep going until we run out of passengers ]

[ Note: When using arrays other than the Input w/o Delineator, is it critical  ]
[ that we clone each element and enque it again. The iteration tracking will   ]
[ let us stop before we go through the array again.                            ]

[ Some things I learned about Taxi in TIO while writing this:                            ]
[  - You can store any passenger at Writer's Depot and Starchild Numerology              ]
[  - You can store any passenger at Heisenberg's and even pick them up again *in order*  ]
[    (You don't start picking up random integers until that queue is gone)               ]
[  - If you try to drop someone at Rob's Rest or Bird's Bench but it's already occupied, ]
[    it won't error out. The passenger just stays in the Taxi which will probably cause  ]
[    a "Too Many Passengers" error eventually. It cost me a week figuring that one out.  ]
