Full Width Text – codegolf.stackexchange.com #JHedzWorlD

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.

Thanks to Dennis for saving 2 bytes. Code:

j⁶⁶ 

Explanation:

j⁶ # Join the list by spaces. ⁶ # Appends a space to the final output.

Sð«J 

Try it online.

Explanation

Sð«J S split string into a list ð« append a space to each element J join 

. $& 

Note the space at the end of the second line.

Haskell, 11 bytes

((:" ")=<<) 

Usage example: ((:" ")=<<) "Code Golf" -> "C o d e G o l f ".

Map each character c to a two element list [c, space] and concatenate everything into a single list.

?=? 

Sample run:

bash-4.3$ gema '?=? ' <<< 'Full width text.' F u l l w i d t h t e x t . 

Thanks to @FryAmTheEggman for saving a byte.

Java, 99 bytes

Can you feel the overhead tonight?

class Tpublic static void main(String[]a)for(char c:a[0].toCharArray())System.out.print(c+" "); 

53 characters for a lambda but that doesn’t meet the program requirement.

s->for(char c:s.toCharArray())System.out.print(c+" ") 

1 byte fewer thanks to @FryAmTheEggman

lSf+ 

Try it online!

Explanation

l e# read line Sf+ e# map "concatenation" (+) with a space (S) as extra parameter e# implicitly display characters in the stack 

Saved 8 bytes thanks to FryAmTheEggman for reminding me about a very useful tip. Code:

,<.I;/@.>6~; 

Or in a more readable form:

 , < . I ; / @ . > 6 ~ ; . . . . . . 

I have no idea why, but this does seem to print a space character in the end. Can definitely be golfed further.

tnZ"v1e 

Try it online!

Explanation

t % implicitly take input string and duplicate it n % number of elements Z" % string with that many spaces v % concatenate vertically (2xN array, where N is input length) 1e % reshape into 1 row. implicitly display 

Seriously, 7 bytes

' ;,@j+ 

Try it online!

Man, that required ending space added 3 additional bytes. Without it, ,' j would work for 4.

Explanation:

' ;,@j+ ' ; push two copies of a single space ,@ push input, swap j+ join on spaces, append a space 

od?.O" "O 

Try it here!

Explanation

o Take character from input d Duplicate top of stack ?. Pop top of stack and jump over the . if truthy, stop otherwise O Output input char " "O Output a space 

Minkolang’s codebox is toroidal, hence there is no need to put an explicit loop in it.

Pyke, 5 bytes

dm+s_ 

Explanation:

d - load ' ' onto the stack m+ - map(add, eval_input_or_not(), " ") s - "".join(^) _ - ^[::-1] 

At the moment Pyke has a bug where if map is given a string, it reverses it

Simple, I just wish that Array.join added the space to the end so I could save 3 bytes.

s=>[...s].join` `+` ` 

Convex, 3 bytes

S*S 

On my phone atm, will update this post later.

sed, 8 bytes

s/./& /g 

When running this from the shell you should quote it of course e.g.

echo Full Width Text | sed 's/./& /g' | od -c
