The Compiler Language With No Pronounceable Acronym, abbreviated INTERCAL, is a very unique programming language. Among its unreproducible qualities are its binary operators.

INTERCAL's two binary operators are interleave (also known as mingle), and select. Interleave is represented with a change (¢), and select is represented with a sqiggle (~).

Interleave works by taking two numbers in the range 0-65535 and alternating their bits. For instance:

234 ¢ 4321
234   = 0000011101010
4321  = 1000011100001
Result: 01000000001111110010001001
Output: 16841865

Select works by taking two numbers in the range 0-65535, taking the bits in the first operand which are in the same position as 1s in the second operand, and right packing those bits.

2345 ~ 7245
2345  = 0100100101001
7245  = 1110001001101
Taken : 010   0  10 1
Result: 0100101
Output: 37

In this challenge, you will be given a binary expression using either the interleave or select operation. You must calculate the result, using the fewest possible bytes.

The expression will be given as a space separated string, consisting of an integer in 0-65535, a space, either ¢ or ~, a space, and an integer in 0-65535.

Input and output may be through any standard system (STDIN, function, command line, etc.). Standard loopholes banned.

Examples:

5 ¢ 6
54

5 ~ 6
2

51234 ¢ 60003
4106492941

51234 ~ 60003
422

This is code golf - fewest bytes wins. Good luck.

EDIT: Since some languages do not support INTERCAL's change (¢) symbol, you may use the big money ($) symbol instead, at a 5 byte penalty.

Python 2, 115 112 bytes

x,y,z=input().split()
d=y<""
f=lambda a,b:a+b and(b%2+5&4-d)*f(a/2,b/2)+(a%2*2+b%2)/3**d
print f(int(x),int(z))

The string on the second line contains a single unprintable character \x7d, the next char after ~.

All hopes of a nice, single lambda get crushed by the input format. There's probably a better way to read in input. Input like "51234 ¢ 60003" via STDIN.

The function f combines the following two recursive functions:

g=lambda a,b:a+b and 4*g(a/2,b/2)+a%2*2+b%2    # ¢
h=lambda a,b:a+b and(b%2+1)*h(a/2,b/2)+a*b%2   # ~

  • \$\begingroup\$ Some great bit bashing! I'm looking at compressing the constant term expression. The expression (a%2*2+b%2)/3**d saves 3 chars but uses the complement d=1-c. Do you have a way to do -~(3*c|b%2) with the complement? At worst it loses 2 chars with 3-3*d. Also, the format and-~x+y can be andy-~x as long as y starts with a symbol or number. \$\endgroup\$

Pretty straightforward, string operations, then conversion back to integer.

print(int(''.join([(i+j,i[:j>'0'])[o>'~']for i,j in zip(*[bin(int(j))[2:].zfill(99)for j in(a,b)])]),2))

Or 165 chars, without limit:

C, 127 123 bytes + 5 penalty = 128

scanf counts the unicode symbol as more than one character which complicates things a lot, so I'm applying the 5-byte penalty for using $.

a,b,q,x,i;main(){scanf("%d %c %d",&a,&q,&b);for(i=65536;i/=2;)q%7?x=x*4|a/i*2&2|b/i&1:b/i&1&&(x=x*2|a/i&1);printf("%u",x);}

The changes from the original version are:

-The test for $ or ~ has been revised from q&2 to q%7. This reverses the true/false values, allowing the code for $ operator to go before the : which means a set of parentheses can be eliminated.

-The i loop now counts down in powers of 2 which is longer, but permits >> to be substituted by / and saves some parentheses.

Original version 127 bytes

a,b,q,x,i;
main(){
  scanf("%d %c %d",&a,&q,&b);
  for(i=16;i--;)
    q&2?
      b>>i&1&&(x=x*2|a>>i&1):    // ~ operator. && used as conditional: code after it is executed only if code before returns truthy.
      (x=x*4|(a>>i&1)*2|b>>i&1); // $ operator
  printf("%u",x);
}

I went with a single loop with the conditionals inside to avoid the overhead of two loops. In both cases I rightshift the bits of the operands down to the 1's bit, and build up the result from the most significant to least significant bit, leftshifting the result (multiplying by 2 or 4) as I go.

I was able to save 1 character however by putting the variable definitions in main. Note: untested. \$\endgroup\$

  • \$\begingroup\$ @LamdaBeta thanks, I couldn't find a macro for >>i&1 but I have managed to golf it another way. Putting the variables as arguments of main causes q to be corrupted on my machine, which is strange. I expect the real problem is with scanf, but because of that I have left them as normal declarations. \$\endgroup\$ Aug 10, 2015 at 13:37
  • \$\begingroup\$ I hadn't thought of that. You are right, q will be corrupted. The reason is that while we learn that main takes two arguments, the count of command-line arguments and an array of the arguments itself, most systems actually provide a third argument (typically called char*envp[]) which describes the environment the code is run in (granting access to EG: environment variables). Thus the third value in main may also be assigned a value by the system, scanf is innocent this time. \$\endgroup\$

  • \$\begingroup\$ @LambdaBeta actually experimentation shows it's a combination of both. With the normal declaration q is guaranteed to be zero, but with the declaration as a function parameter q contains 32-bit garbage. That wouldn't be a problem if I assigned a value to q, but scanf with "%c" only overwrites the least significant 8 bits of the garbage, leaving the other 24 undefined. I might get lucky on another compiler! \$\endgroup\$ Aug 10, 2015 at 21:55

f=(x,o,y)=>+eval(`'0b'+(b(y)+b(x)).replace(/^1|${o=='~'?1:'(.)'}(?=.{16}(.)())|./g,'$2$1')`)

Test:

Javascript ES6 (1 argument) 135 133 bytes

b=x=>(65536|x).toString`2`
f=s=>([x,o,y]=s.split` `)|eval(`'0b'+(b(y)+b(x)).replace(/^1|${o=='~'?1:'(.)'}(?=.{16}(.)())|./g,'$2$1')`)

Test:

;[f('234 ¢ 4321'),f('2345 ~ 7245')]=="16841865,37"

PS: New line is counted as 1 byte as it can be replaced by ;.

Python 3, 157 bytes

a,x,y=input().split()
i=int
b=bin
print(i(''.join(([c for c,d in zip(b(i(a)),b(i(y)))if d=='1'],[c+d for c,d in zip(b(i(a))[2:],b(i(y))[2:])])['¢'==x]),2))

Full and explanatory version can be found on my pastebin.

  • \$\begingroup\$ You can same a few chars by removing spaces around '==' operator, before 'if' and by passing 'base' as positional argument. \$\endgroup\$

  • \$\begingroup\$ Thank you, that and some others have saved 15 chars! but the doubled way of formatting the return is still to much. \$\endgroup\$ Aug 10, 2015 at 9:19
  • \$\begingroup\$ Also, do you use 4 spaces per indent? One (or tab) is enough. \$\endgroup\$

    \$\begingroup\$ @BeowulfOF Unless otherwise specified, you can submit a full program or a function. Generally, which is shorter will depend on the way your language parses the specific input for the challenge (ruby is surprisingly clumsy with numbers from stdin for example). You also have two possible ways to output: stdout or return value, which are applicable to both (though return values from programs are rare.) \$\endgroup\$ Aug 10, 2015 at 10:24

Mathematica, 155 bytes

f=IntegerDigits[#,2,16]&;
g=#~FromDigits~2&;
¢=g[f@#~Riffle~f@#2]&;
s=g@Cases[Thread@{f@#,f@#2},{x_,1}->x]&;
ToExpression@StringReplace[#,{" "->"~","~"->"s"}]&

Evaluates to an anonymous function taking the string as input. Line breaks added for clarity.

f and g convert to/from base 2. Riffle does exactly what interleave is supposed to. I wanted to use Select for select but Cases is better unfortunately. The last line is a bit of trickery; spaces are changed to ~ which is Mathematica's infix operator, then the string is eval'd.

Go, 186 bytes

func c(a,b uint)(o uint){for i:=0;i<16;i++{o|=(a&1<<(2*i+1))|(b&1<<(2*i))
a>>=1
b>>=1}
return}
func s(a,b uint)(o uint){for i,j:=0,0;i<16;i++{if b&1>0{o|=a&1<<j;j++}
a>>=1
b>>=1}
return}

Attempt This Online!

c is interleave, and s is select.

Explanations

Interleave

func c(a,b uint)(o uint){       // init return value in `o` with zero value
for i:=0;i<16;i++{              // for each bit (in the uint16)...
o|=                             // OR to `o`...
   (a&1                         // the last bit of `a`
       <<                       // shifted left by
         (2*i+1))               // the current bit * 2 + 1
                 |              // OR-ed with
                  (b&1          // the last bit of `b`
                      <<        // shifted left by
                        (2*i))  // the current bit * 2
a>>=1;b>>=1}                    // discard the last bit of `a` and `b`
return}

Select

func s(a,b uint)(o uint){ // init return value in `o` with zero value
for i,j:=0,0;i<16;i++{    // for each bit (in the uint16)...
if b&1==1{                // if the current bit in `b` is 1...
          o|=             // OR to `o`...
             a&1          // the last bit of `a`
                <<j       // shifted over by the number of 1s so far
                   ;j++}  // increment the number of 1s
a>>=1;b>>=1}              // discard last bit of `a` and `b`
return}

  • \$\begingroup\$ @Pacmanboss256 It does not, because it does not parse STDIN. These are 2 functions, each of which does the operations described in the OP. Doing input parsing as well would just add some code that would call this submission's code anyway. \$\endgroup\$
