# Question
Title: Somewhere On The Tube ...But On Which Lines?
The London Underground A.K.A. The Tube is the oldest underground railway in the world, it currently consists of eleven lines\* servicing 267 named stations (strictly 269\** stations since "Edgware Road" and "Hammersmith" each occupy two locations)

### The challenge

Output the names of the lines servicing a station given by name as input.

**Input:**
A string or list of characters

* This may be assumed to be a *valid* station name (as listed in the code-block below).
* You may assume any `&` in the input will *consistently* be the word `and` (or `And`) instead if you wish, just state it clearly in your answer.

**Output:**
*Separated* output listing those of the eleven lines servicing that station:

* A list of strings, a list of lists of characters, printed text, a string, a list of characters; if in doubt ask.
* You may *consistently* output the word `and` (or `And`) in place of any `&` if you wish, just state this clearly in your answer.
* With the caveat that if printing or returning a string or list of characters that the separator-substring used is not present in any of the line names (including the `&` or `and` or `And` used) - this therefore excludes the use of a single space character as the separator.

**The Tube Network**:
\- Note: This is the final state, even if it happens to contain a spelling mistake (unless addressed prior to any answers)

```

...the eleven line names are:

```
Bakerloo
Central
Circle
District
Hammersmith & City
Jubilee
Metropolitan
Northern
Piccadilly
Victoria
Waterloo & City

```

* Transport For London do manage other train lines too, some may also be referred to as being part of "The Tube" (most likely the "Docklands Light Railway" or "DLR") but we shall stick to the eleven listed here.

\** The linked Wikipedia page currently states 270, but I believe they are mistakenly counting the second location of Canary Wharf even though it only services the "DLR")

Heaps of imaginary brownie points (and most likely many upvotes too) for a golfed submission using Mornington Crescent (a compatible IDE is available here)!

This is , so the shortest code in bytes wins per language and the shortest solution wins (don't let golfing languages put you off golfing in other languages). Have fun!

# Answer
# Mathematica 8+, 266 bytes

```
t=Merge[Cases[<<ExamplePages/TripPlanning.nb,_@v__~_~{_->l_}:>(#->l&/@{v}),-1],Union@@#&];
x(r=t@@Nearest[Keys@t]@StringReplace[__~~"d Lane"|"ket"->"Royal Oak"]@x;DeleteCases[
  If[x<>r[[1]]//StringFreeQ@"sm",{},{"Circle"}]⋃r,"Overground"|"Docklands Light Rail"])

```

This solution originally had the same number of bytes as there are stations. I suppose it could be golfed down another 50 or so bytes, but this seemed like a fitting place to stop for now.

## Introduction

Mathematica is well known for its large standard library and access to a large online "computable knowledge base." I brazenly searched Wolfram|Alpha hoping to easily find the relevant transit data, but although it understands the domain of my query, the data is not yet available.

Fortunately, Mathematica's extensive built-in documentation comes with neat examples. Several of those pages just happen to use the London Underground network to demonstrate graph-related functionality. We will use the graph from the "Trip Planning" featured example due to its short name.

>

Here are other cool uses of the same network.

I do not believe that programmatically accessing Mathematica's own documentation falls into the "Fetching from an external source"-type loopholes.

## Import the example page

We can import the example page as a notebook expression:

```

```

> ```
> Notebook[{Cell[ ... ], ... }, Saveable -> False, ...]
>
> ```

It is possible to extract the whole graph from deep inside the notebook expression:

```
g = FirstCase[<< ExamplePages/TripPlanning.nb, _Graph, , -1];
VertexList[g]

```

> ```
> {"Acton Central", "Acton Town", "Aldgate", ...}
>
> ```

Note that the vertices of the graph are just the station names. The edges have a custom `"Lines"` property that is a list of strings representing the lines that pass between its two stations:

```
# -> PropertyValue[{g, #}, "Lines"] & /@ EdgeList[g]

```

> ```
> {...,
>  "Acton Town" <-> "Chiswick Park" -> {"District"},
>  "Acton Town" <-> "Ealing Common" -> {"District", "Piccadilly"},
>  ...}
>
> ```

Now, we could find all the lines passing through a vertex by getting all its incident edges from `IncidenceList[g, vertex]`, mapping `PropertyValue[{g, edge}, "Lines"]` over them, and so on.

However, we will skip the above method and save many bytes by pattern matching for the relevant part of the `Graph` constructor – the `Properties` option.

## Extract the lines

The `Graph` constructor has the following format:

```
Graph[
  {v1, v2, ...},
  {e1, e2, ...},
  Properties -> {
    v1 -> {propertyName -> propertyValue},
    e1 -> {propertyName -> propertyValue},   (* one edge property *)
    ...
  }
]

```

(You can see this by inspecting `FullForm[g]` or reading the source code of `TripPlanning.nb` – for its full path, run `FindFile["ExamplePages/TripPlanning.nb"]`.)

Here is an example of one edge property:

```
UndirectedEdge["Embankment", "Waterloo"] -> {"Lines" -> {"Bakerloo", "Northern"}}

```

Let's turn this expression into a compact pattern:

```
UndirectedEdge[v1_, v2_]  ->      {"Lines" -> lines_}
UndirectedEdge[v1_, v2_]  ~Rule~  {"Lines" -> lines_}
UndirectedEdge[v__]       ~Rule~  {_       -> lines_}
             _[v__]       ~Rule~  {_       -> l_    }
             _@v__        ~_~     {_       -> l_    }

             _@v__~_~{_->l_}

```

## Make a lookup table

Now we can match `v1`, `v2`, and `lines`, but we want `{v1 -> lines, v2 -> lines}`. Helpfully, `Cases` can simultaneously match a pattern and transform it.

```
Cases[notebook,  _@v__~_~{_->l_} :> (# -> l & /@ { v }),  -1]
                 [ the pattern ]    [ the replacement ]

```

This produces a list of the form `{{v1 -> lines, v2 -> lines}, {v1 -> lines, v3 -> lines}, ...}`. Finally, we merge the list by vertex:

```
t=Merge[Cases[...], Union@@#&];

```

In under 90 bytes, we have produced an almost-perfect lookup table for each station's lines.

```
t=Merge[Cases[<<ExamplePages/TripPlanning.nb,_@s__~_~{_->l_}:>(#->l&/@{s}),-1],Union@@#&]

```

> ```
> <| "Embankment"       -> {"Bakerloo", "Circle", "District", "Northern"},
>    "Waterloo"         -> {"Bakerloo", "Jubilee", "Northern", "Waterloo & City"},
>    "Brondesbury"      -> {"Overground"},
>     ... |>
>
> ```

## Fix typos

Unfortunately, some station names are misspelled or missing.

Fuzzy string matching should take care of the typos. We can find the `Nearest` misspelled station name to the input station name:

```
Nearest[Keys@t]

```

Replace inputs of `"Wood Lane"` and `"Shepherd's Bush Market"` (new stations) with `"Royal Oak"`, since those three stations share the same lines:

```
StringReplace[__ ~~ "d Lane" | "ket" -> "Royal Oak"]

```

Compose those functions to get the fake station name, look up its lines in the table, and store in `r`:

```
r=t@@Nearest[Keys@t]@StringReplace[__~~"d Lane"|"ket"->"Royal Oak"]@x

```

## Fix outdated

The network is also slightly outdated due to the Circle Line overhaul.

If the input station is `"Hammersmith"` or if the lookup table returns only `{"Hammersmith & City"}`, then add `"Circle"` to the lines.

```
If[x <> r[[1]] // StringFreeQ@"sm", {}, {"Circle"}] ⋃ r

```

## Remove extraneous lines

The graph contains some lines that we don't care about, so remove them:

```
DeleteCases[..., "Overground"|"Docklands Light Rail"]

```

That's it!

## Try it! (with workarounds)

If you want to play around with my solution but don't have Mathematica, you can use the free Wolfram Programming Cloud. Go here, click `Create a New Notebook`, then wait a moment.

Unfortunately, the platform has some limitations that prevent my notebook-importing code from working. Here are some crude workarounds:

Since the example page is not there, we can try to abuse the copy-input-to-clipboard function from the online documentation. I used my browser's developer tools and saw that a request was made to `http://reference.wolfram.com/language/example/Files/TripPlanning.en/i_1.txt` (warning: large). However, the platform's proxy doesn't resolve the domain `reference.wolfram.com`, so I just did it manually.

```
gWorkaround = ToExpression[
  FirstCase[
    Import["http://140.177.205.163/language/example/Files/TripPlanning.en/i_1.txt",
      {"HTML","XMLObject"}],
    XMLElement["pre", _, {a_}] :> a,
    ,-1
  ],
  InputForm, Hold];

```

Paste this in first and press `shift+enter` to execute. Now replace `<<ExamplePages/TripPlanning.nb` with `gWorkaround`.

*(1) From the specification: Let mathInt be the mathematical integer value that is represented by Z in radix-R notation \[...\]. **If R is not 2, 4, 8, 10, 16, or 32, then mathInt may be an implementation-dependent approximation** to the mathematical integer value that is represented by Z in radix-R notation.*

### How?

Below is a step-by-step decoding example for the input `s = "St. James's Park"`.

**Step #1**

We first inflate the primary lookup table (from 503 to 2,328 bytes) by expanding all its padding characters. These characters are encoded with an ASCII code greater than 92, whereas payload data is using the range 48-90.

```
tbl = " 5Kd5_9 5c4[...]"
  .replace(
    /./g, c =>
      c.repeat((n = c.charCodeAt()) < 92 || n - 91)
  )

```

**Step #2**

We remove all non-alphabetic characters from the input string:

```
str = s.replace(/\W|\d/g, '')

```

which gives `"StJamessPark"`.

**Step #3**

We parse the resulting string as a base-36 quantity:

```
id = parseInt(str, 36)

```

which gives `3793395908848905700` (this is the approximated result returned by Chrome V8).

**Step #4**

We compute the hash value:

```
hash = id * 79 % 2777 % 2328

```

which gives `533`.

**NB**: Due to loss of precision, this result is not mathematically correct (it should be `184`). But the lookup table was -- of course -- built the same way, so that's the one we're expecting.

**Step #5**

We retrieve the ASCII code of the character at this position in the primary lookup table:

```
code = tbl.charCodeAt(hash)

```

which gives `58` (this is the character `':'`).

**Step #6**

We use this value to extract a 2-character string from the secondary lookup table:

```
msk36 = '7c1w0o74[...]'.substr(code * 2 - 96, 2)

```

which gives `0c`.

**Step #7**

We parse this string as a base-36 quantity:

```
msk = parseInt(msk36, 36)

```

which gives `12`.

**Step #8**

Finally, we filter the station list according to the bits set in `msk`, starting with the least significant one:

```
"Bakerloo,Central,Circle,District,[...]".split`,`.filter((_, i) => msk >> i & 1)

```

In our example, `msk` holds `12`, which is `00000001100` in binary. So we keep the 3rd and 4th stations, which leads to the final result: `[ 'Circle', 'District' ]`.

## Explanation

To distinguish the station name with as few as many characters, I fiddled a little and found out that if I took the 22nd, 23rd and 24th character of the MD5 hash, it would be unique except for ONE collision: `ddb` could stand for `Heathrow Terminals 1, 2, 3` as well as for `Dagenham Heathway`.

To refer to the 11 tube line names, I just use a hexidecimal digit from 0 through A.

Then I created a comma separated list of the MD5 hash substrings, with the corresponding tube line digits next to it. But I did leave out `Heathrow Terminals 1, 2, 3` from the list to avoid the collision.

Example: `fe538` means that whatever station who's md5'd name has the characters `fe5` on the 22nd, 23rd and 24th place, runs the tube lines referred to by `3` and `8`. Meaning `Acton Town` runs tube lines `District` and `Piccadilly`.

Then I wrote a simple function that checks the input. MD5 hashes it. Takes the 22nd, 23rd and 24th character. Matches it against the list that I created. And shows the corresponding tube names. With the expection of `ddb` off course, which is hardcoded to `Piccadilly`, when the given string starts with an `H`.

## Edits

* Replaced `array()` with `[]` for -5 chars
* Used gzdeflated and base64\_encoded my code, so I can now use `eval(gzinflate(base64_decode()))` for -309 chars

I have no doubt this can be golfed *much* more, the problem is Cinnamon Gum's lack of complete docs. (@quartata pls this has great chance of being amazing troll lang) I might dig into the source code to see if there's anything that can be beneficial to this.

This is the Python script I hacked together to generate the compressed string.

**Explanation** The input is encoded as a binary representation (8-bits ASCII code for each letter of the input word) when completing the input word by spaces at right if the length of the word is less than 26. I already done the same representation for all possible inputs and find the minimal bits that differentiate the outputs. The code looks at these specific bits to decide on the output.
