Print the Retro Rocket

Question

(inspired by this SO question)

You are given as input a single positive integer n.

In as few characters as possible, output a rocket in ASCII art with a head, a tail, and a body composed of n segments. There should be no trailing spaces or newlines.

The head and the tail of the rocket are always the same for any value of n. The body consists of two different types of segments which alternate. The examples should make the structure of the rocket clear.

Output for n = 1:

     /**\
    //**\\
   ///**\\\
  ////**\\\\
 /////**\\\\\
+=*=*=*=*=*=*+
|\/\/\/\/\/\/|
|.\/\/..\/\/.|

|./\/\../\/\.|
|/\/\/\/\/\/\|
+=*=*=*=*=*=*+
     /**\
    //**\\
   ///**\\\
  ////**\\\\
 /////**\\\\\

Output for n = 2:

     /**\
    //**\\
   ///**\\\
  ////**\\\\

+=*=*=*=*=*=*+

     /**\

Output for n = 3:

This should work in the online interpreter.

How it works

After pushing the Unicode string, the snippet

6e4b127b:c~

converts the string from base 60000 to base 127, casts to string and evaluates the result.

The code that get executed is the following:

"..."          " A binary string of length 42.                                            ";
122b7b         " Convert from base 122 to base 7.                                         ";
"\n *./\|"f=   " Replace each digits with the corresponding character.                    ";
60/~           " Split into chunks of length 60 and dump the resulting array.             ";
               " The stack now contains the rocket's head and a body half.                ";
[_W%[\]_W%]    " Push an array of the body half and the reversed body half, a reversed    ";
               " copy of that array and collect both array into another one.              ";
Nf*Nf+         " Join each array of body halves separating by LFs and append LFs.         ";
ri:I*           " Repeat the resulting array I := int(input()) times.                     ";
I<W%           " Keep the first I bodies and reverse their order.                         ";
\a_@\++        " Prepend and append the rocket head/tail.                                 ";
'+"=*"6*'+N+++ " Push S := '+=*=*=*=*=*=*+\n'.                                            ";

Try it online

Takes the input n via STDIN.

I'll add an explanation at some point later. Basically it's all just a bunch of loops in a very naive way. To alternate between the two different body parts, I've got a nested loop over the part and a loop over 0 and 1. Then I just add the outer iterator and the inner one, and use their parity to decide between upwards or downwards pointing triangle.

Answer 3

Ruby, 203

n,q=$*[0].to_i,"\\/"
h,r,m=1.upto(5).map{|i|(?/*i+"**"+?\\*i).center 14},?++"=*"*6+?+,3.times.map{|i|?|+?.*i+q*(3-i)+?.*(2*i)+q*(3-i)+?.*i+?|}*"\n"
p=m.reverse.tr q,"/\\"
puts h,([r,m,p,r,p,m]*n)[0,3*n],r,h

Ungolfed

I think in this case it's beneficial to have an non-golfed version.

n      = $*[0].to_i
head   = 1.upto(5).map { |i| ("/"*i + "**" + "\\"*i).center 14 }
ridge  = "+" + "=*"*6 + "+"
middle = 3.times.map { |i| "|" + "."*i + "\\/"*(3-i) + "."*(2*i) + "\\/"*(3-i) + "."*i + "|" }.join "\n"
piddle = middle.reverse.tr "\\/", "/\\"

puts head
puts ([ridge,middle,piddle,ridge,piddle,middle]*n)[0,3*n]
puts ridge, head

Explanation

I doubt this is anywhere near efficient, but it was fun nonetheless.

• Input is taken from ARGV.
• h contains the "head" and "tail" of the rocket, r contains the "ridges" that separate the different parts of the rocket and m and p are the top and bottom parts of the "body" of the rocket.
• The body is constructed by cycling through the Array ["ridge", "top of body", "bottom of body", "ridge", "bottom of body", "top of body"] and taking the first 3*n elements.
• puts makes sure everything gets its own line.

Answer 4

Python, 120 + 77 + 1 = 198 characters

This ended up being the wrong approach, but I had already finished when Martin posted his answer.

H,L,T,B=open("R","rb").read().decode('zip').split("X")
n=input()
for p in[H]+([B,T,L,T,B,L]*n)[:3*n][::-1]+[L,H]:print p

Requires a file R (+1 for filename) of 77 bytes, which you can generate as follows:

>>> open('R','wb').write('eJxNjMENwDAIA/+ZIm8i4Qm6Bw+PwvDFQRUFydwJwd5VMOO6ILqIRjE+LsEI4zw2fSKJ6Vzpmt4p\ndVlnRikoVWqrK+8s/X1ivozIJuo=\n'.decode('base64'))

Answer 5

JavaScript (E6) 252 257

Overuse of string.repeat

F=p=>{
  R=(n,s='.',a='')=>a+s.repeat(n)+a;
  for(i=f=o=m=n='';++i<6;)
    o+=f+R(6-i,' ')+R(i,u='/')+'**'+R(i,t='\\'),
    f='\n',
    i<4?m+=f+R(2,R(4-i,t+u,R(i-1)),'|',n+=f+R(2,R(i,u+t,R(3-i)),'|')):0;
  s=f+R(6,'=*','+'),
  console.log(o+s+R(p&1,q=m+n+s)+R(p/2,n+m+s+q)+f+o)
}

Answer 6

JS, WIP, 252b or 173 chars

It's not a function, so you have to set the value of n at the beginning (3 here), then execute it in the console or in nodeJS.

Here's the 252b version:

n=3;r=a="     /**01    //**001   ///**0001  ////**00001 /////**00000";b="1+=*=*=*=*=*=*+1";for(c=[d="|0/0/0/0/0/0/|1|.0/0/..0/0/.|1|..0/....0/..|",d.split("").reverse().join("")];n--;)r+=b+c[n%2]+1+c[1-n%2];(r+b+a).replace(/0/g,"\\").replace(/1/g,"\n")

And here's the 173 chars version (using http://xem.github.io/obfuscatweet/)

n=3;eval(unescape(escape('').replace(/uD./g,'')))

Answer 7

Javascript (ES3): 243 219 bytes

R=function(n){for(a='',i=5;i--;t=a+=s+'\n')for(s='**',j=6;j--;b=['|../\\..|./\\/\\.|/\\/\\/\\','|\\/\\/\\/|.\\/\\/.|..\\/..'])s=i<j?'/'+s+'\\':' '+s+' ';for(;a+='+=*=*=*=*=*=*+\n',n;)a+=(b[n&1]+b[--n&1]).replace(/[^|]+/g,'$&$&|\n');return a+t}
