Description du défi

En métrique de taxi , une distance entre deux points est définie comme:

Considérons une matrice avec uniquement des zéros et des uns:

Mappons chacun 1à la distance au plus proche différent 1 dans la matrice (bien sûr, en supposant que la distance entre deux lignes / colonnes adjacentes est égale à 1):

Pour ce défi, étant donné une matrice, trouvez sa carte des distances comme indiqué ci-dessus.

Remarques

Vous pouvez prendre des contributions dans n'importe quel format raisonnable
En dehors de 0et 1vous pouvez choisir deux valeurs distinctes
Vous pouvez supposer qu'une matrice n'est pas vide (contient au moins une ligne de longueur supérieure ou égale à 1), ainsi qu'elle est rectangulaire
Vous pouvez également supposer qu'il y a au moins deux valeurs véridiques présentes dans la matrice (sinon, la sortie n'est pas définie)
Vous pouvez écrire un programme complet ou une fonction
Au lieu de renvoyer une nouvelle matrice, vous pouvez modifier une matrice existante
C'est du code-golf , alors faites en sorte que votre nombre d'octets soit aussi bas que possible!

Essayez-le en ligne! Ou vérifiez tous les cas de test .

Explication

Pour voir les résultats intermédiaires, il peut être utile d'insérer X#(afficher la pile) entre deux états quelconques.

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

Essayez-le en ligne!

Je suppose qu'aucun humain ne veut essayer de lire ce code, alors essayez-le en ligne avec des commentaires, des étiquettes significatives et une sortie plus lisible!

Entrée: chaîne représentant un tableau. La chaîne doit être composée de 3 caractères: 0, |représentant sauts de lignes, et tout plus de chiffres positifs d'une (PDGTO). J'aime utiliser 8. OP permet la saisie dans n'importe quel format raisonnable et je pense que cela est admissible. La chaîne n'a pas à être formatée en un tableau rectangulaire, mais elle sera supposée alignée à gauche quelle qu'elle soit.

Sortie: tableau de valeurs indiquant la distance minimale de la cabine de taxi de chacune PDGTOà l'autre la plus proche PDGTO.

Le deuxième format de sortie est clairement beaucoup plus facile à lire, mais il ajoute également 7 octets au programme et c'est du code-golf , après tout. Il aurait été possible de revenir en arrière à la fin et de supprimer tous les zéros de fin au lieu de simplement remplir les 0valeurs, mais cela aurait ajouté encore plus d'octets et était considéré comme un coût inacceptable.

Voici le texte du code non-golfé avec des commentaires, de meilleures étiquettes et une sortie plus claire:
(C'est la même chose que vous obtenez avec le lien ci-dessus.)

[ 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.  ]
