# Build a mob of suspiciously happy lenny faces ( ͡° ͜ʖ ͡°)

I was going through a bizarre thread on Reddit, and came across this:

( ͡°( ͡° ͜ʖ( ͡° ͜ʖ ͡°)ʖ ͡°) ͡°)

It's representing a group of people smiling somewhat suspiciously.

(In the challenge below though, spaces to the left of the right eyes were dropped somehow while I was writing the challenge. Note the spec).

Your goal is to create a group of smiling lenny faces n deep with the following rules:

1. At depth one, a full face (( ͡° ͜ʖ ͡°)) is shown.
2. At depth two, half faces are shown. On the left side, a little over half the face (( ͡° ͜ʖ) is represented. On the right however, the right side is shown, and the mouth is omitted (ʖ ͡°))
3. Any deeper, and only the sides of head and eyes are shown (( ͡° and ͡°). There's a space between the eye and left side of the head, but there are, despite appearances, no spaces on the right side. The spacing is due the ͡ character which messes with things a bit.

Input:

• n, showing how many layers deep of faces to show.
• n will always be in the range 0 <= n <= 500. You are not required to handle anything outside of this range.
• n may be offset by 1 so that 0 means one face instead of no faces. You'll need to handle -1 then though.

Output:

• A string, or character array, or anything remotely comparable (like a list of single-character strings in Python/Javascript). It can also be printed directly. Trailing white-space is fine.

You can submit a complete program, or a function.

Since it's difficult to see what characters are involved, here's it laid out in Python:

>> [ord(c) for c in '( ͡° ͜ʖ ͡°)']
[40, 32, 865, 176, 32, 860, 662, 32, 865, 176, 41]

>> [ord(c) for c in '( ͡°( ͡°( ͡° ͜ʖ( ͡° ͜ʖ ͡°)ʖ ͡°)͡°)͡°)']
[40, 32, 865, 176, 40, 32, 865, 176, 40, 32, 865, 176, 32, 860, 662, 40, 32, 865, 176, 32, 860, 662, 32, 865, 176, 41, 662, 32, 865, 176, 41, 865, 176, 41, 865, 176, 41]

Here's an extraordinarily naive recursive reference implementation (posted on my Github). I tried to keep it as plain as possible for clarity; but there's a lot of duplication

I posted it externally because I wanted to wrap it in a spoiler in case people don't want to see a reference, but that complicates copying the code. I figure it's not important to the challenge really, so it isn't a big deal if it goes down I can paste it here if it's deemed important.

This is code-golf, so the least number of bytes in each language wins.

• It looks even more suspicious when rendered on TIO. :p Aug 15, 2019 at 22:13
• The spec and the test cases seem to be inconsistent; the spec has a space at the beginning of the right part of the latter depths, while the test cases do not. Aug 15, 2019 at 22:14

7 bytes off thanks to xnor

(!!)$"":x:iterate(4#8)(7#6$x)
x="( ͡° ͜ʖ ͡°)"
(a#b)y=take a x++y++drop b x


Try it online!

To start we assign ( ͡° ͜ʖ ͡°) to a string x for convenience.

x="( ͡° ͜ʖ ͡°)"


Then we build a list of the answers and index it to find the solution. This is done by hardcoding the first two answers as the first two elements of the list and then iterating a function that adds the first 4 characters and the last 4 characters to front and back of the string across the third answer.

(!!)$"":x:iterate(4#8)(7#6$x)


We also have the special function (#) which adds a specified amount of ( ͡° ͜ʖ ͡°) to the front and back of a string:

(a#b)y=take a x++y++drop b x

Or try it with the following snippet for a better rendering.

o.innerHTML += '"' + f(n) + '"\n';
}
pre { font-family:Arial }
<pre id="o"></pre>

### Commented

In the following code, we use the character set "eEMN" (eyebrow, eye, mouth and nose respectively) in order to preserve the formatting.

f = n =>           // f is a recursive function taking the number n of remaining
// faces to draw
n ?              // if n is greater than 0:
"( eE" + (     //   append the left cheek + a space + the left eye
--n > 1 ?    //   decrement n; if it's still greater than 1:
f(n)       //     append the result of a recursive call
:            //   else (n = 0 or 1):
"MN" + (   //     append the mouth and the nose
n ?      //     if n = 1:
f(n)   //       append the result of a recursive call
+ "N " //       followed by the nose + a space
:        //     else (n = 0):
" "    //       append a space and stop recursion
)          //
)              //
+ "eE)"        //   append the right eye + the right cheek
:                // else:
//   the special case n = 0 is reached only if the original
""             //   input is 0; just return an empty string

Generate the cheeks, but use <s and >s because (s and )s would need to be quoted. A space in the middle ends up between the middle man's nose and left eye.

 >>

If the man in the middle has a man on his left, give that man a nose and a space between it and his left eye.

<(?=<? )
< ͜ʖ


Add the mouth and nose to the man in the middle and the man to his right if any. We don't see the left eye of the man to his right so he doesn't need a space, and we gave the man in the middle a space on the first stage.

# Inform 7, 262 bytes

To say x:say "[Unicode 865][Unicode 176]".
To say y:say Unicode 860.
To say z:say Unicode 662.
To say p (N - number):say "( [x][p N minus 1][x])".
To say p (N - 2):say "( [x] [y][z][p 1][z][x])".
To say p (N - 1):say "( [x] [y][z] [x])".
To say p (N - 0):say "".


This takes advantage of Inform 7's function overloading: the most specific overload will be run, and the function that takes a number (any integer) as its argument is less specific than the function that takes the number two (and only two) as its argument.

There are some repeated bits of text, like "( [x]", which could potentially be abstracted as functions of their own—but I7 is so verbose, defining a new function takes more bytes than this would save! The only places defining a new function seems to save bytes is for the non-ASCII characters, since the syntax for printing them is even more verbose than the syntax for function definitions.

Boilerplate to run this:

Foo is a room. When play begins: say p 7.


Replace 7 with a non-negative integer of your choice.

The more observant among you will have noticed that the middle face has its nose generated twice which is why I'm printing in such a way that they overlap.
