挑战说明

在出租车度量中，两点之间的距离定义为：

考虑一个只有零和一的矩阵：

让我们每个映射1到到最接近的距离不同 1的矩阵（当然，假设相邻两行/列之间的距离等于1）：

对于这个挑战，给定一个矩阵，找到它的距离图，如上所示。

笔记

您可以采用任何合理的格式输入
除了0，1您还可以选择任何两个不同的值
您可以假设矩阵是非空的（至少包含一行长度大于或等于1的行），并且它是矩形的
您还可以假设矩阵中至少存在两个真实值（否则，输出未定义）
您可以编写完整的程序或函数
您可以修改现有矩阵而不是返回新矩阵
这是代码高尔夫球，所以请让您的字节数尽可能少！

在线尝试！或验证所有测试用例。

说明

要查看中间结果，X#在任何两个语句之间插入（显示堆栈）可能会有所帮助。

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

在线尝试！

我以为没有人愿意尝试阅读该代码，因此可以在线使用注释，有意义的标签和更具可读性的输出进行尝试！

输入：表示数组的字符串。该字符串必须由3个字符组成：0，|代表换行符，并且任何大于1的正数（PDGTO）。我喜欢用8。OP允许以任何合理的格式输入，我相信这是合格的。该字符串不具有格式化为矩形阵列，但它会被假定为左对齐不管它是什么。

输出：一组值，显示从出租车PDGTO到最近的出租车之间的最小距离PDGTO。

第二种输出格式显然更容易阅读，但它也向程序添加了7个字节，毕竟这是 code-golf。可以返回结尾并删除所有尾随零，而不是简单地填充0值，但这将增加更多的字节，这被认为是不可接受的成本。

[ 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          ]

[ 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.  ]
