Full Width Text

Question

Full width text is text that has a space after every character, including the last one. For instance, the first sentence of this question becomes:

F u l l w i d t h t e x t i s t e x t t h a t h a s a s p a c e a f t e r e v e r y c h a r a c t e r , i n c l u d i n g t h e l a s t o n e . 

Write a program that takes a line in text from standard input and outputs it as full-width text to standard out.

• wizzwizz4: Usually you should allow functions too, or you exclude a lot of languages (e.g. JavaScript).
• Dennis: We have a few defaults for I/O that are based on community consensus. While you are entitled to override them, insisting on STDIN/STDOUT for I/O invalidates a bunch of answers (which assumed that the defaults apply) and make the task downright impossible in other languages (they don't have standard streams).
• BlueRaja - Danny Pflughoeft: That is not what fullwidth text is.
• Ludovic Frérot: @BlueRaja-DannyPflughoeft is right. Full Width text is about underlying character encoding ( 2 bytes encoded ) required by some language ( i.e. ideograms ). In Unicode the notion of half and full size is called Unicode block
• Erik the Outgolfer: @LudovicFrérot Actually, these are not ideograms, these are chinese english letters.

Answer 2

C#, 52 bytes

Manual, straightforward approach, without using Linq.

s=>{var r="";foreach(var c in s)r+=c+" ";return r;};

Anonymous method which gets every character from the string and adds a space after each one.

Full program:

using System;
namespace FullWidthText
{
 class Program
 {
 static void Main(string[] args)
 {
 Func<string, string> f =
 s =>
 {
 var r = "";
 foreach (var c in s)
 r += c + " ";
 return r;
 };
 Console.WriteLine(f("Full width text is text that has a space after every character, including the last one."));
 }
 }
}

Answer 4

C#, 35 bytes

s=>string.Join(" ",s.ToList())+" ";

C# lambda where the input and the output are string. You can try it on .NetFiddle.

• VisualMelon: This requires a using System.Linq derivative, which should either be included or the language marked as LinqPad or similar.

Answer 5

Python 3, 39 bytes

print("".join([x+" "for x in input()]))

• wnnmaw: You could just join with a " " rather than insert it with the comprehension. Then all you need to worry about is the trailing space at the end. print(" ".join(input())+" ") gets you down to 28 bytes
• manatwork: This is now exact duplicate of Raffi's answer, which reached this format 1 day 01:30:09 hour earlier.
• Yytsi: @manatwork I see. Should I change my old answer back or something? Thanks for telling!
• manatwork: Just improve it more. ;) In meantime I would revert to the previous version – it demonstrates the usage of a very popular Python feature, which has better chances for positive votes than a duplicate.
• Yytsi: @manatwork Very good point! Reverted it. Back to 39 bytes :D

Answer 6

Python 3, (削除) 31 (削除ここまで) 28

print(' '.join(input())+' ')

I know i'm late on this one, and definitely not a winner, but thought i'd try it out.

Edit: Switched to python 3. Thanks to CatsAreFluffy for saving 3 bytes!

• Zach Gates: You can cut one byte by removing the space after print.
• CalculatorFeline: Or just switch to Python 3 (and cut 3 bytes): print(' '.join(input)+' '). raw_input is more expensive than parens with print.

Python 3, (削除) 95 93 92 80 32 26 (削除ここまで) 30 bytes

Saved a byte thanks to @caird coinheringaahing

Saved bunch of bytes from @DJMcMayhem + My idea

print(' '.join(input())+' ')

Takes input, splits it, then prints a join with spaces

This is my first time golfing.

• caird coinheringaahing: Welcome to the site! You can remove a byte by removing the space after the : as well as taking a look at these tips for Python golfing
• DJMcMayhem: You could get this down to a one-liner: print(''.join(i+' 'for i in input())
• Mercury Platinum: @DJMcMayhem, made it even shorter :)
• Jo King: Does this print a space after the last character? And do you need the list() part?
• Mercury Platinum: oh, one second.

SMBF, 9 bytes

Note the trailing space. Uses the space in the code rather than creating a 32 in a cell.

,[.<.>,] 

The tryitonline.net interpreter appears to have a bug and loop indefinitely with this, so it only works in my Python interpreter. Changing the SMBF source code (currently on line 171) inside the Python code is required.

This code makes use of most interpreters wrapping to 255 if the number is negative.

Previous solution:

Explanation:

++++[>++++++++<-] |Leaves the second cell with the number 32, the ASCII Code for a space.
+[,.>.<] |Simple loop, gets the input, outputs it and adds a space.

Suggestions are welcome.

• ovs: 24 bytes. The initialization part is taken from this page
• Dust: Cool, very nice. I have problems understanding your program though. Could you explain it to me?
• ovs: The code makes use of the fact that most brainfuck implementations use wrapping 8-bit cells. If you decrement a cell that is zero, you get to 255. Here is a simple example.
• Jo King: The , should be at the end of the loop, otherwise you print an extra nul byte. Try it online!

 T" "}}} //push 2 spaces after every char, push to the bottom of the stack for later
 l&T &M:&0)?t //push original length and store, every loop decrement and if it is greater than zero, repeat
 rH//reverse stack and output the whole stack as characters

• Jo King: 7 bytes. Mostly because you can combine all the loops into one loop over the input
• KrystosTheOverlord: @JoKing Wow, that is really smart using the E function! Also I just realized that it only needs one space, and that I forgot to add spaces after the last characters, sorry!
• KrystosTheOverlord: @JoKing Almost managed 6 bytes, but it prints entirely backwards... iEH@`

The Befunge-98 answer is pretty long, so here is a shorter one. Basically the same answer as this Befunge-93 answer by Sp3000, but ends up being half as long, thanks to Befunge-98s ~ reflecting on EOF.

One thing that bugged me is, that when you run it on multi line input, every line but the first will be indented (since the linebreak will be followed by a space as well), so here is a version (11 bytes), that doesn't have that problem.

"$args "

There are already a couple of PowerShell answers to this question, but I thought I'd throw mine into the mix. It takes splatter input from a command line argument. It also assumes that $ofs is equal to one space, which it is by default.

• mazzy: Great! The codegolf allow you to use an char array instead of a string. Therefore, 8 bytes

Answer 25

Commodore C64 BASIC, 39 Tokenised BASIC bytes, 42 PETSCII characters with keyword abbreviations

0INPUTA$:FORI=1TOLEN(A$):?MID$(A,ドルI,1)" ";:NEXT

On running this listing, the interpreter will expect an input of strings which when the return key is pressed, will store the text entered into the variable A$. It will then iterate over each position of the string to its length and PRINT it, proceeded by a white space, and then will continue at the next cursor position until the final character of the string is printed (this will be followed by a space too).

Some notes: A Commodore C64 screen is 40 characters wide by default, and the maximum number of characters that may be stored in a string is 255, however, when using INPUT the interpreter will only accept a total entry of 77 characters without some trickery (80 characters if you delete the ? prompt, enter 80 characters and then cursor up two lines and press the RETURN key).

See screenshot for this in action.

Answer 26

Pascal, 90 bytes

This is a full program suitable for a processor supporting "Standard Pascal" and/or "Extended Pascal" as defined by ISO standards 7185 and 10206 respectively. As per specification it takes a line (not many lines). Note, calling EOLn(input) causes an error if EOF(input) is true prior invocation of EOLn. Hence it must be guaranteed that input contains at least an end‐of‐line marker.

program p(input,output);begin while not EOLn do begin write(input↑,' ');get(input)end end.

We can add −10 bytes if it is guaranteed that input is a non‐empty line:

program p(input,output);begin repeat write(input↑,' ');get(input)until EOLn end.
