Sign that word 2!

Question

Sign that word 2!

Not that long ago, I posted a challenge called Sign that word!. In the challenge, you must find the signature of word, which is the letters put in order (e.g. The signature of this is hist). Now then, that challenge did quite well, but there was one key issue: it was WAY too easy (see the GolfScript answer). So, I've posted a similar challenge, but with more rules, most of which have been suggested by PPCG users in the comments on the previous puzzle. So, here we go!

Rules

1. Your program must take an input, then output the signature to STDOUT or the equivalent in whatever language your using.
2. You are not allowed to use built-in sorting functions, so stuff like $ in GolfScript is not allowed.
3. Multicase must be supported - your program must group letters of both uppercase and lowercase together. So the signature of Hello is eHllo, not Hello as you are given by the GolfScript answer on the first version.
4. There must be a free interpreter/compiler for your program, which you should link to.

Scoring

Your score is your byte count. Lowest byte count wins.

Answer 1

Pyth, 10 bytes

sm@+drd1zG

Try it online: Demonstration

Explanation:

             implicit: z = input string
 m       G   map each letter (variable d) of the alphabet to:
   +drd1        d + upper(d)
  @     z       filter z for these two letters
s            sum, join to a string

Answer 2

Haskell, 51

f s=[x|(a,b)<-zip['a'..'z']['A'..],x<-s,x==a||x==b]

The zip creates a list of pairs of characters [('a','A'), ...('z','Z')]. Because of truncation, the second endpoint doesn't need to be specified. For each pair in the list, we take the letters in the input string s that are either of the two characters in the pair.

Answer 3

Python 3, 72 70 bytes

s=input()
print("".join(d*(ord(d)&31==c)for c in range(27)for d in s))

Assumes the input consists of only [a-zA-Z].

Answer 6

JavaScript (ES6), 71 74

Limited to A-Za-z (see comment by @Matthieu M)

Edit Too used to compose a single expression with commas, to avoid 'return'. Here an output is required, so I can use a simple for and forget about commas.

Using array comprehension the byte count is 73, but that is not valid EcmaScript 6 anymore

Usual note: test running the snippet on any EcmaScript 6 compliant browser (notably not Chrome not MSIE. I tested on Firefox, Safari 9 could go)

f=w=>{v=[];for(c of w)v[n=parseInt(c,36)]=(v[n]||'')+c;alert(v.join``)}

<input id=I value='Hellzapoppin'><button onclick=f(I.value)>-></button>

Answer 7

Javascript, 112 194 bytes

r=[];t=[];a=s.split('').map(function(x){t[i=parseInt(x,36)]?t[i].push(x):t[i]=[x];return i;});while(l=a.length)r[l-1]=t[a.splice(a.indexOf(Math.max.apply({},a)),1)].pop();console.log(r.join(''))

This is far away from "golfed" but I'm a bit busy right now, just editted to remove sort.

Answer 8

Python 3, 64

A small improvement on Sp3000's answer, which uses the idea of iterating iterating the character indices, and for each one, iterating through the input to take characters that match up to case.

c=1
for d in(input__+'~')*26:print(end=d[ord(d)&31^c:]);c+=d>'z'

This uses a single loop, looping through the input 26 times. The separator ~ is used to know when to go to the next character index c. To whether character d matches value c up to case, the last five bits of the bit-value of d are xor-ed with c, with a 0 indicating a match.

Then, the character d is printed exactly when the result is 0, with an empty string otherwise.

Answer 9

Python 2.7, 114 106 bytes

l=[0]*123
for e in raw_input():l[ord(e)]+=1
print''.join(chr(j)*l[j]for i in range(26)for j in(i+65,i+97))

Logs the presence of a char in a 123 length array(for including both A-Z and a-z ranges) and then iterates through it to get the non-zero entries.
Inefficient, but more efficient than brute forcing it(but longer :().

Testing it-

<< HelloWorldhi
>> deHhillloorW

Answer 10

PHP, 275 270 bytes

<?php
for($i=65;$i<123;$i++){$v[$i]=chr($i);}foreach(str_split($argv[1])as$c){$a=array_search($c,$v);if($a<97){$p[]=($a+32);$z[]=$a;}else{$p[]=$a;}}foreach($p as$chr){$m=min($p);if($z[0]+32==$m){echo chr($m-32);unset($z[0]);}else{echo chr($m);}unset($p[array_search($m,$p)]);}

Explanation:
The code generates an array with every letter in the alphabet, which has its ASCII Value as Array Key. Afterwards the code generates a new array which contains the ASCII Values of the Input. Then the lowest Value gets printed out and gets removed.

Usage:
Call the script with an argument: php -d error_reporting=0 script.php Hello

Ungolfed Version:

<?php
$input = $argv[1];
$valueArray = [];
for($i=65;$i<123;$i++) {
    $valueArray[$i] = chr($i);
}
$new = str_split($input);
foreach($new as $char) {
    if(array_search($char, $valueArray)<97) {
        $newArray[] = (array_search($char, $valueArray)+32);
        $checkArray[] = array_search($char, $valueArray);
    } else {
        $newArray[] = array_search($char, $valueArray);
    }
}
foreach($newArray as $chr) {
    if($checkArray[0]+32 == min($newArray)) {
        $string .= chr(min($newArray)-32);
        unset($checkArray[0]);
    } else {
        $string .= chr(min($newArray));
    }
    $key = array_search(min($newArray), $newArray);
    unset($newArray[$key]);
}

echo $string;

Any advices are greatly appreciated.

Answer 11

Haskell, 83 53 bytes

import Data.Char
f y=[c|x<-[' '..],c<-y,toLower c==x]

Usage: f "HelloWorldhi" -> "deHhillloorW".

How it works: let y be the input string

[ |x<-[' '..]                  ]  -- for every x from Space to the last Unicode character
             ,c<-y                -- loop through all character c from the input string
 c                ,toLower c==x   -- and keep those where the lowercase version equals x

Edit: 30 bytes saved, imagine that! Thanks @Mauris.

Answer 12

Python 3, 61 bytes

A new answer for a different technique!

z=['']*42
for c in input():z[ord(c)&31]+=c
print(*z,sep='')

Noting that ord('a')&31==ord('A')&31 and that ord('z')&31==ord('Z')&31, we can simply create an array of empty strings and for each character add it to the array index of its ASCII value &31. When you print it, it will be sorted.

Limited to input a-zA-Z.

Answer 13

Python 3, 97 92 bytes

from itertools import*;print(*min(permutations(input()),key=lambda z:str(z).lower()),sep='')

The best way to sort is clearly to generate all permutations, and then pick the minimum, which just happens to be sorted :)

The strings are lowercased before comparison to abide by the 'case-aware' rules.

Warning: may be very slow with big strings.

An interpreter is located here.

Answer 14

Python 3, 118 bytes

i=input();i,x=map(list,(i,i.lower()))
while x:q=min(x);x.remove(q);q=[q.upper(),q][q in i];i.remove(q);print(q,end="")

Could be golfed much shorter, I know

Answer 15

Powershell, 164 Bytes

I'm sure there's a cleaner way to do this, but I couldn't come up with anything else. Just takes the input as a character array, does an insertion sort, and spits out the output. Loses horribly, even to other non-golfing languages.

Code:

$a=[char[]]($args[0]);For($u=1;$u-lt$a.Count;$u++){$n=$a[$u];$l=$u;while(($l-gt0)-and((""+$a[$l-1]).CompareTo(""+$n)-gt0)){$a[$l]=$a[$l-1];$l--}$a[$l]=$n};$a-join''

Usage:

PS C:\scripts> .\sign-word-2.ps1 tTHhis
hHistT

Expanded & Explained:

$a=[char[]]($args[0])               # Takes command-line argument, recasts as char array
For($u=1;$u-lt$a.Count;$u++){       # Performs a quick-n-dirty insertion sort
  $n=$a[$u]
  $l=$u
  while(($l-gt0)-and((""+$a[$l-1]).CompareTo(""+$n)-gt0)){
  # Ugly, ugly code here. String.CompareTo(String) is case-insensitive, but
  # because we cast as a char[], Char.CompareTo(Char) is case-sensitive ...
  # So, need to do an on-the-fly re-casting as a string with ""+
    $a[$l]=$a[$l-1]
    $l--
  }
  $a[$l]=$n
}
$a-join''             # Without the -join'', it would print out the chars with a space between

Answer 16

Julia, 61 bytes

f=s->s>""?(k=indmax([s...]%32);f(s[k+1:end]s[1:k-1])s[k:k]):s

Julia will display it as a string output if you call it in the REPL. If it has to print out to STDOUT, then it needs 78 bytes:

x->(f=s->s>""?(k=indmax([s...]%32);f(s[k+1:end]s[1:k-1])s[k:k]):s;print(f(x)))

An interpreter for Julia can be found here. Another one, which I've already put some code into, is here. Note that, with the second one, you will need to make the terminal (at the bottom) visible by dragging the boundary up. Clicking "execute" will make it run in the terminal at the normal command line (and thus won't show the output if called without println). Alternatively, you can just type julia into the terminal itself, then handle everything inside the REPL that will come up.

And for a bit of extra fun, here are some other implementations

Gnome Sort (83 bytes):

s->(for m=2:endof(s),n=m:-1:2 s[n]%32<s[n-1]%32&&(s=s[[1:n-2,n,n-1,n+1:end]])end;s)

Bubble sort, with some register reuse tricks to shave bytes here and there; the .COM file runs in DosBox, receives the input from command line and prints the output to standard output.

Answer 21

PHP, 106 bytes

The code:

$c=count_chars($argv[1]);$r=str_repeat;for($i=64;++$i<91;)echo$r(chr($i),$c[$i]),$r(chr($i+32),$c[$i+32]);

There is nothing special in the code; count_chars() produces an array indexed by ASCII codes that contains the number of occurrences for each ASCII character. The rest is a dull iteration over this array.

Example of execution:

$ php -d error_reporting=0 sign.php qwertyuioplkjhgfdsazxcvbnmQWERTYUIOPLKasdfJHGFDSAZXCVBNM
AaaBbCcDddEeFffGgHhIiJjKkLlMmNnOoPpQqRrSssTtUuVvWwXxYyZz

An extra byte can be saved using PHP 7: replace $c[$i] with ($c=count_chars($argv[1]))[$i] and remove the assignment of $c from the beginning of the program.

Pip, 18 14 bytes

GitHub repository for Pip

Seems there's no competing with Pyth, but this is pretty respectable.

FcAZ OcQUC_FIa

Works only on strings containing a-zA-Z. For each letter of the alphabet, uses a filter operation to grab the letters from the input string that equal that letter case-insensitively:

                    a <- cmdline arg, AZ <- string containing uppercase alphabet (implicit)
FcAZ                For each character c in AZ:
           FIa      Filter characters of a on the following lambda function:
      UC_           Uppercase of character...
         Qc         ... is equal to c
     O              Output the resulting list, joined on empty string by default

Two notes:

• The space is necessary; otherwise, the sequence AZO would scan as A ZO instead of AZ O;
• The program doesn't output a trailing newline. To add one, put an x at the end of the code (thereby printing an empty string after the loop is done).

Sample run (using the x variant):

(If a function were OK, it would have been 5 bytes ⍋⍤⌈⊇⊢.)

⍋ can be controversial here, because the challenge says "built-in sorting functions not allowed" and ⍋, called "Grade", is definitely related to sorting but it doesn't sort the input by itself. Instead, it gives a list of indices which, when used to index into the original input, results in the sorted array:

      x←10 50 20 40 75
      ⍋x
1 3 4 2 5
      x[⍋x]
10 20 40 50 75

This can be also used to implement "sort-by", if we index into a different array other than x:

      'abcde'[⍋x]
acdbe

How it works

s⊇⍨⍋⌈s←⍞  ⍝ Full program
     s←⍞  ⍝ Take a line of string input and assign to s
    ⌈     ⍝ Uppercase the letters
   ⍋      ⍝ Grade up; find the sorting order
s⊇⍨       ⍝ Index into the original string s,
          ⍝ essentially sorting the string in the case-insensitive order

Set intersection in APL is essentially "erase the items in the left argument that do not appear in the right argument", so the duplicates in the left argument is preserved.

How it works

∊⍞∘∩¨⎕A,¨⌊⎕A  ⍝ Full program.
     ⎕A,¨⌊⎕A  ⍝ Pair each char in ⎕A (uppercase letters) with its lowercase
 ⍞∘∩¨         ⍝ Take intersection of entire input and each pair of chars
∊             ⍝ Flatten

œ.ΔlÇ¥dP

Try it online or verify a few more test cases.

Explanation:

œ         # Get all permutations of the (implicit) input-string
 .Δ       # Find the first permutation which is truthy for:
   l      #  Convert it to lowercase
    Ç     #  Convert each character to its ASCII codepoint
     ¥    #  Get the deltas / forward-differences of those codepoint integer
      d   #  Check that each difference is >= 0
       P  #  And check that all of them are truthy
          # (after which the found string is output implicitly as result)
