Print "N NE E SE S SW W NW"

Question

This seems almost trivial, but since after some effort I was not able to beat the literal solution in J, I thought it might make a decent challenge (though, to be clear, this is not a J-specific challenge).

Title says it all. You simply need to write a program, or function (taking no arguments) that returns or prints:

N NE E SE S SW W NW

You may use newlines in place of spaces.

A no-argument function returning an array of strings such as

['N', 'NE', 'E', 'SE', 'S', 'SW', 'W', 'NW']

is also acceptable.

The letters may be upper or lower case, but may not be mixed.

Answer 1

bash (24 bytes)

using brace expansion

echo N {N,,S}E S {S,,N}W

is the same length as hard coding

echo N NE E SE S SW W NW

however it becomes more interesting when outputing more points of the compass

echo N NNE NE ENE E ESE SE SSE S SSW SW WSW W WNW NW NNW

brace expansion

echo N {{N,,E}N,,{E,,S}S}E S {{S,,W}S,,{W,,N}N}W

otherwise if order could be changed, (17 bytes), the trick is that without quotes the empy string parameter disappears

echo {N,,S}{W,,E}

Since it's a bit much to expect you to read all that, let me give a quick overview of my approach. The main idea is to store 3 copies of the characters N,E,S,W at various stations on the Circle line, via Bank - Hammersmith. These characters are constructed from the start of a station name at Charing Cross. Then, construct   from the middle of a well-chosen station name using Mile End and Charing Cross, and store it at Bank so that it can be collected at Hammersmith in the concatenation. Finally, concatenate the characters one by one at Paddington, copying them again via Bank - Hammersmith if they are need to be reused later.

---

I think the current solution is fairly close to optimal with this strategy, at least in terms of number of stations visited: just 2 times I used a station only for transit:

1. to get to Seven Sisters (via Victoria station)
2. and to get back to Mornington Crescent (via Bank).

All other station visits were, if I didn't forget one, either storing/retrieving something useful or (part of) using the stations ability.

As for the line lengths, I've tried to pick the shortest names on Circle Line, but there may be a minor improvement there. It's possible that storing something on District can shave off a few bytes.

Excel Formula, 59 57 bytes

The following should be entered as an array formula (Ctrl+Shift+Enter):

=SUBSTITUTE(ADDRESS(1,{14,369,5,499,19,517,23,387},4),1,)

After entering the formula as an array formula, highlight it in the formula bar and evaluate it using F9 to return the result, for example:

Before:

After:

How it works

The ADDRESS function returns a string representing a reference based on two parameters, row and col. The third parameter controls what type of reference is returned, an absolute or relative reference. For example, =ADDRESS(1,2,4) returns "B1".

We can supply an array to ADDRESS and use it as an array formula to return multiple results, for example =ADDRESS(1,{1,2,3},4) returns "A1","B1","C1".

Therefore, in my answer, the array supplied to ADDRESS are just the column numbers relating to the required compass points, e.g. Column 14 is column N, Column 369 is column NE.

However, we are not finished here since all the returned references have the row included, for example, N1, NE1. Therefore, we simply use SUBSTITUTE to remove the 1 from all references.

Try it online! Link is to verbose version of code... which is just the string to be printed, as the auto-deverbosifier takes care of the string compression.

Printing the string uncompressed takes 19 bytes, since Charcoal prints printable ASCII literally. The best algorithmic answer I could come up with unfortunately takes 20 bytes:

Try it online! Outputs using array format (would cost two bytes to join the elements on spaces).

This code will first create the characters "EN SW" into the memory and then move back and forth to print them. The space is in the middle, because it is printed most often. N and S and W and E never appear together so they are on opposite sides of the memory. For optimization some of the final decrements happen during the output phase.

Answer 15

Commodore BASIC (TheC64Mini, C64, C128, VIC-20 etc.) 28 Tokenized BASIC bytes used

 0 PRINT"N NE E SE S SW W NW

In Commodore BASIC, you do not require the closing quotation mark on PRINT or LET statements as the interpreter will auto-close it, this saves one BASIC token.

Alternatively, one may simply use direct mode as follows:

Commodore BASIC 23 PETSCII characters (+ RETURN to execute)

?"N NE E SE S SW W NW

I'm not sure how to count the number of bytes used in this instance as according to the interpreter ? and PRINT use the same number of bytes, and there is no program stored in memory.

So, outputting in lower-case with newlines is better than default (upper-case with spaces).

    int mult = 1;

    for (int i = 0; i < (int)actions.length(); ++i)

Try it online (with raw spaces, tabs, and new-lines only).

Explanation:

1. Push the unicode values minus constant 84 for the characters "WN W WS S ES E EN N" to the stack (note that the string is pushed in reversed). In addition, I use a few copies of previously pushed values to save bytes where possible.
2. Then start an infinite loop, which does the following:
   1. Add the constant 84 to the current unicode value
   2. Print it as character to STDOUT

The constant 84 is generated by this Java program which I wrote for another challenge I answered in Whitespace.

''.join(' SEWN'[0xe0619042210504>>i*3&7]for i in range(19))

The magic number is the joined three-bit indexes into the character string, reverse order so we can start iterating at the LSB.

---

I spent a while trying to shrink the magic number, but repeating the character string via multiply to allow for extra indexes doesn't work out due to needing to encode for space - best I got for overlapping indexes in the lookup added more characters to the string than digits removed from the magic number (including a couple of unfortunate don't-cares in the middle):

"NeSw"it;?↺₍h₂a₀oụ

Try it online!

Semi-port of my Jelly solution. Generates each direction.

"NeSw"                Let the input variable be "NeSw".
      i               Take a pair [element, 0-index] from it,
       t              extract the index,
        ;?↺₍          and rotate the input variable left by that many places.
            h₂        Keep only the first two elements of the rotation,
              a₀      take a prefix (nonempty, shortest first) of it,
                o     sort (putting uppercase before lowercase),
                 ụ    and fold to uppercase.

Barely beats my original...

"NNEESESSWWNW"ḍ₄ḍᵐc

Try it online!

Outputs as a list. ḍ₄ḍᵐc saves two bytes over writing out seven spaces and making the entire predicate a string literal, so at least it ties PHP...

"NNEESESSWWNW"         The string "NNEESESSWWNW"
              ḍ₄       split into quarters
                 ᵐ     with each quarter
                ḍ      split in half
                  c    and concatenated
                       is the output.
