Quack the Angry Duck

Question

No one is quite certain what the emoticon >:U is intended to represent, but many scholars believe it looks like an angry duck. Let's assume that's the case.

Task

Given an integer n between 0 and 3 inclusive, print or return

quack

if n = 0,

>:U

if n = 1,

     U   U
>  : U   U
 >   U   U
>  : U   U
      UUU

if n = 2, or

                  >:U         >:U
>:U               >:U         >:U
   >:U       >:U  >:U         >:U
      >:U         >:U         >:U
         >:U      >:U         >:U
      >:U         >:U         >:U
   >:U       >:U  >:U         >:U
>:U               >:U         >:U
                     >:U>:U>:U

if n = 3.

You can assume the input will always be valid. There should be no leading space in the output, but any amount of trailing space is fine. Ducks (with the possible exception of @cobaltduck) have no tolerance for loopholes. Shortest code in bytes wins.

Answer 1

CJam, 108 90 85 bytes

"quack"">:U":D"scT¦{$ì"{269b22bSf*D}:F~[ZYB].*s.+s5/"ÿ3nÜïS{JÐø¦yûn"F*33/z]ri=zN*

Note that some characters are unprintable. Try it online!

Background

The first two outputs are incompressible in CJam.

Compressing the last output is straightforward. After stripping all linefeeds, we can split the resulting string at occurrences of >:U, and compute the length of each resulting string of spaces.

That results in the array

[18 9 0 15 9 3 7 2 9 6 9 9 9 6 9 6 9 9 3 7 2 9 0 15 9 21 0 0 0]

which we can store efficiently by converting it from base 22 to base 269, yielding the digits

[255 12 51 110 220 239 83 123 74 208 248 166 121 251 110 17]

Since each digit is less than 256, we can store it as a single byte.

Finally, compressing the third output becomes easier if we transpose lines and columns:

 > > 
  >  

 : : 

UUUU 
    U
    U
    U
UUUU

Counting once more the spaces between non-whitespace characters, we get the array

[1 1 3 8 1 6 0 0 0 5 4 4 0 0 0 0 0]

which becomes

[115 159 99 84 166 123 36 236 6]

when transcoded from base 22 to base 269.

How it works

"quack"   e# Push the first output.

">:U":D   e# Push the second output, and save it in D.

e# Push [115 159 99 84 166 123 36 236 6] as bytes.

"scT¦{$ì"

{         e# Define a code block:
  269b22b e#   Transcode from base 269 to base 22.
  Sf*     e#   Replace each digit with a string of that many spaces.
  D       e#   Push D.
}         e#
:F~       e# Save the block in F. Execute it.
[ZYB]     e# Push [3 2 11].
.*        e# Vectorized repeat; push [">>>" "::" "UUUUUUUUUUU"].
s         e# Flatten the array of strings.
.+        e# Append the nth character to the nth string of spaces.
s5/       e# Flatten and split into chunks of length 5.

e# Push [255 12 51 110 220 239 83 123 74 208 248 166 121 251 110 17] as bytes.

"ÿ3nÜïS{JÐø¦yûn"

F         e# Execute F.
*         e# Join the resulting array of strings of spaces, separating by ">:U".

z         e# Zip; transpose rows with columns.

]         e# Wrap the entire stack in an array.
ri        e# Read a token from STDIN and interpret it as an integer.

Not actually meant to be the shortest, I just thought it would be fun to try in Java.

Creates a list of string variables representing common strings, then creates an array of all the outputs, then prints the right one.

String a(int y){String n="\n",d=">:U",A=" ",B=A+A,C=B+B,D=C+C,a="U"+B+" U"+n,G=D+A,H=C+B,c=d+G+d+n,E=B+A,F=C+E;String[]z={"quack",d,C+A+a+">"+B+": "+a+" >"+E+a+">"+B+": "+a+C+B+"UUU",D+D+B+c+d+D+F+c+B+A+d+F+d+B+c+H+d+G+c+G+d+H+c+H+d+G+c+E+d+F+d+B+c+d+D+F+c+D+D+C+A+d+d+d};return z[y];}

Ungolfed:

String a(int y) {
    String n = "\n", d = ">:U", A = " ", B = A + A, C = B + B, D = C + C,
            a = "U" + B + " U" + n, G = D + A, H = C + B, c = d + G + d + n,
            E = B + A, F = C + E;
    String[] z = { "quack", d, C + A + a + ">" + B + ": " + a + " >" + E + a + ">" + B + ": " + a + C + B + "UUU", D + D + B + c + d + D + F + c + B + A + d + F + d + B + c + H + d + G + c + G + d + H + c + H + d + G + c + E + d + F + d + B + c + d + D + F + c + D + D + C + A + d + d + d };
    return z[y];
}

Code

Dammit, way too long, but it's at least something:

">:U"VI3Qið16×7166b1ð:0Y:DUJ,Yð13×JD?X,3838b1ð:0Y:D?X,16255b1ð:0Y:D?X,16367b1ð:0Y:4F?X,}ð21×Y3×J,}¹2Qið4×" U   U"©J,">  :"®JD," >  "?®,,ð6×'U3×J,}¹iY,}"quack

Try it online!

---

Explanation

The first part of the code exists of ">:U"V, which sets Y to that string. After that, we just check if the input is equal to 3. That is done at the I3Qi part. If equal, we print the giant magpie:

N = 3

It first starts with ð16× which just pushes 16 space characters. After that, there is a number 7166b. This covers the ">:U " part, with a little help from Retina :). I used this script to convert the string to a binary number. After that, we get to the 1ð:0Y: part, which replaces every 1 with a space character and every 0 with Y, which has been set to >:U. After that, we Duplicate this string, store it in X using U and Join the stack. We pop this using ,, which prints the full string with a newline. All the others after that are all based on the same principe. The if statement ends at the second }.

The full conversion can be found here.

N = 2

We now check if the input is equal to 2. This is done at the ¹2Qi part. After that, if equal, we push the space character 4 times using ð4×. After that, we push the " U U" string and store it using © (idea blatantly stolen from Jelly :p). We again Join the stack and print this with a newline. After that, we push the "> :" string, retrieve the " U U" using ®, Join the stack and Duplicate this string and print these both on the same line.

Short quiz, what will this do: " > "?®,?

After printing the above string, we get the duplicate of the second line of the face, and print this (since it's the same as the 2nd line).

The last part covered by this case is:

ð6×'U3×J,

ð6×        # Push the space character × 6
   'U3×    # Push the "U" character three times
       J,  # Join and print pop with a newline

N = 1

This one is easier to explain:

¹1QiY

¹1Qi   # Check if the input is equal to 1
    Y  # Push the magpie face
       # This is then implicitly printed

N = 0

¹0Qi"quack

¹0Qi        # Check if the input is equal to 0
    "quack  # Weird sound what magpies make
            # Implicitly printed

Oh, geez. If I wanted something to show off the power of methods, I got it.

' 'V1+m

VVVZ2m78m2mVV7m

Try it Online!

How this works is by calling various methods throughout itself. The explanation is below:

' 'V1+m
' 'V      Save character literal ' ' as a permanent variable.
    1+    Add one to the top item of the stack (input + 1)
      m   Go to that index of code.

'kcauq'Z
'kcauq'   Push 'quack' to the stack.
       Z  Output everything in the stack as a char.

'U:>'Z
'U:>'Z    Ouput ">:U" with the same method as the previous line.

Now on to some more... interesting lines.

58m5m6m'   > 'Z5m6m'UUU'68m
5              Push space, push 4
 8m            Call the 8th line index.
               As we will soon see, the 8th line index duplicates the space
               the number of times specified by the number just before the call 
               (4 in this case)
   5m          Call the 5th line index.
               The 5th line index outputs the 'U   U' and a newline.
     6m        Call the 6th line index.
               The 6th line index outputs '>  : U   U' and a newline.
'   > 'Z       Output ' >   '.
        5m6m   Same method calls as before.
'UUU'          Push 'UUU'.
     68m       Push 6, then call the 8th line index. This gives us the correct padding.

f3+bm9mamcm98m2m6bmcmam9mf6+8m3\[2m]
f3+              Push 18.
   bm            Call the 11th line index.
                 The 11th line index calls the 8th line index (which we've already seen
                 in action) and then the 7th line index, which you can find and explanation
                 for below (it does a lot)
     9m          Call the 9th line index.
                 The 9th line index outputs '>:U               >:U         >:U' (explanation lower)
       am        Call the 10th line index.
                 ...I'm gonna stop explaining these and just tell you to go to the lines now. :P
         cm      Call the 12th line index.
9                Push space, push 9.
 8m              Call the 8th line index (explained below and before).
   2m            Call the 2nd line index.
     6           Push 6.
      bm         Call the 11th line index. We've finished up to '>:U      >:U         >:U' now.
cm               You guessed it! Call the 12th line index. (explanation below)
  am             Call the 10th line index. (explanation below)
    9m           Call the 9th line index. (explanation below)
f6+              Push space, push 19 21.
   8m            Call the 8th line index. (explanation below)
     3\[2m]      Call the 2nd line index thrice.

All of the rest of these methods are supporting methods now.

a'U   U'Z       Output 'U   U' followed by a newline.

' :  >'Z5m      Output '>  : U   U' followed by a newline.

Z2m98ma2m
Z               Output everything currently in the stack.
 2m             Call the 2nd line index.
   9            Push space, push 8.
    8m          Call the 8th line index. (explained below)
      a         Push a newline to the stack.
       2m       Call the 2nd line index.
                This handles the biggest angry duck face's faces showing the eyebrows and eyes.

\VZ
\V    Push space as many times as the top item specifies.
  Z   Output everything in the stack.

2mfbm
2m      Call the 2nd line index.
  f     Push space, push 14.
   bm   Go to the 11th line index.
        This handles the mouth and some parts of the eyebrows of the biggest duck face.

VVVZ2m78m2mVV7m
VVVZ              Output 3 spaces (and whatever was pushed before it)
    2m            Call the 2nd line index.
      7           Push space, push 6.
       8m         Call the 8th line index. (explained... above)
         2m       Call the 2nd line index.
           VV     Push 2 spaces.
             7m   Call the 7th line index.

8m7m     This is pretty damn self-explanatory if you've read this far.

68m2m9bm
6            Push space, push 5.
 8m          Call the 8th line index.
   2m        Call the 2nd line index.
     9       Push space, push 9.
      bm     Call the 11th line index.

" '1]®r'1">:U" r"%d"_SpZ}ÃgU

Contains an unprintable. Test it online!

How it works

The first two strings are not compressed at all. The third is compressed simply by replacing each runs of spaces with its length, then " U3U" with "z". The last one is more complex:

1. Replace each run of 2-9 spaces with its length.
2. Replace >:U with 1.
3. Replace 191\n with 4. (4 isn't used anywhere else in the string.)
4. Map each valid byte code (10-255, or 0A-FF) to the character with that char code.

The resulting string is only 21 19 bytes long, but the decompression takes up another 31 29.

After decompressing the strings, we simply take the item at position U, the input. (The array is arranged [0,3,2,1] because there's a bug which makes it count from the end of the array instead of the beginning.)

[                      // Create an array of the following:
  "quack"              //  "quack".

  "c)`+«öÂ[@=^Gñ`1]o2" //  Take this string (contains an unprintable).
                       //  Map each char to its char code.
                       //  This produces "994196431712461949164619431712419649931112".
  r'4#¿+R              //  Replace each "4" with the char code of "¿" (191) + a newline.

  "4z>2:z >2z>2:z6UUU" //  Take this string.
  rz" U3U\n"           //  Replace each "z" with " U3U\n".

®              Ã       // Map each item by this function:

r"%d"_SpZ}             //  Replace each remaining digit Z with Z spaces.

gU                     // Get the item at index -U, wrapping.

This uses decimal numbers to encode indices 0...3 to the four characters for cases 2 and 3. The decimal numbers could perhaps be compressed using base-64 encoding, but quack!

For the case 3 a very nice trick suggested by @Adnan is used: define binary sequences to encode each row, where 0 and 1 correspond to space and >:U respectively.

Non-competing since Cinnamon Gum was created after this challenge.

Try it online.

Explanation

The first byte l specifies the mode: in this case it tells Cinnamon Gum to enter lookup table mode. Cinnamon Gum then decompresses the rest of the string (which has been compressed with zopfli --deflate) into this:

0&quack;1&>:U;2&     U   U
>  : U   U
 >   U   U
>  : U   U
      UUU;3&                  >:U         >:U
>:U               >:U         >:U
   >:U       >:U  >:U         >:U
      >:U         >:U         >:U
         >:U      >:U         >:U
      >:U         >:U         >:U
   >:U       >:U  >:U         >:U
>:U               >:U         >:U
                     >:U>:U>:U

It then splits by ;, puts each key-value pair (with & as delimiter) in a dictionary, and outputs dictionary[input].

GML, 265 bytes

A port of @kittycat3141's excellent answer, with the suggestion to golf it further with two new variables (which I named G and H) by @VoteToClose. I also managed to shorten it further with GML's relatively loose syntax.

d=">:U"A=" "B=A+A;C=B+B;D=C+C;G=D+A;H=C+B;a="U"+B+" U"+"#"c=d+G+d+"#"E=B+A;F=C+E;x[0]="quack"x[1]=d;x[2]=C+A+a+">"+B+": "+a+" >"+E+a+">"+B+": "+a+H+"UUU"x[3]=D+D+B+c+d+D+F+c+B+A+d+F+d+B+c+H+d+G+c+G+d+H+c+H+d+G+c+E+d+F+d+B+c+d+D+F+c+D+D+C+A+d+d+d;return x[argument0]
