# How high can you count?

## Challenge:

Your task is to write as many programs / functions / snippets as you can, where each one outputs / prints / returns an integer. The first program must output the integer 1, the second one 2 and so on.

You can not reuse any characters between the programs. So, if the first program is: x==x, then you may not use the characters x and = again in any of the other programs. Note: It's allowed to use the same character many times in one program.

### Scoring:

The winner will be the submission that counts the highest. In case there's a tie, the winner will be the submission that used the fewest number of bytes in total.

### Rules:

• You can only use a single language for all integers
• Snippets are allowed!
• To keep it fair, all characters must be encoded using a single byte in the language you choose.
• The output must be in decimal. You may not output it with scientific notation or some other alternative format. Outputting floats is OK, as long as all digits that are shown behind the decimal point are 0. So, 4.000 is accepted. Inaccuracies due to FPA is accepted, as long as it's not shown in the output.
• ans =, leading and trailing spaces and newlines etc. are allowed.
• You may disregard STDERR, as long as the correct output is returned to STDOUT
• You may choose to output the integer to STDERR, but only if STDOUT is empty.
• Symbol independent languages (such as Lenguage) are disallowed
• Letters are case sensitive a != A.
• The programs must be independent
• Whitespace can't be reused
• You must use ASCII-digits in the output

Explanations are encouraged!

• The language Headsecks only cares about the lower three bits of every character and would trivially achieve a score of 64. It's partially symbol-independent, but not completely. I think the last rule should cover partially symbol-independent languages as well, but I'm not sure how to phrase it. – Dennis Jun 4 '17 at 22:45
• Regarding the snippet rule, do we still need to include usings/imports? And are static imports allowed (without making them part of the snippet that is)? – Kevin Cruijssen Jun 6 '17 at 17:45
• @KevinCruijssen you can omit boilerplate stuff that's needed for every programs/functions. For instance, you don't need #include <iostream> and other boilerplate stuff in C++. You do need from numpy import *. Note: I'm not a programmer, so I don't know all the nuances. We can discuss in chat if something is unclear :) – Stewie Griffin Jun 6 '17 at 18:05
• You have the right to vote however you like @tuskiomi, but in my opinion it's a good rule. Whitespace characters are just bytes, just as any other character. Why should they be treated differently? Also, the language Whitespace would win by a landslide, since it contains only space, tab and line shift. Thanks for saying why you downvoted though :-) – Stewie Griffin Aug 18 '17 at 17:31
• @StewieGriffin I would at least allow spaces, but hey, I'm not you. – tuskiomi Aug 18 '17 at 18:30

Try it online - slightly weird/inconvenient. And #14 uses stack depth, so it must occur after printing the others.

### Explanation:

1. Use some comparisons to obtain True, which evaluates to -1, then take the absolute value. See #2 for a description of j. This uses linefeeds to separate the tokens.
1. J is a loop counter, used for inner loops, and is also some large number when not inside a user-defined loop. Checking if it equals itself returns -1 (True). Using subtraction, I obtain 2. This uses tabs to separate the tokens.
1. This uses vertical tabs

(ASCII 11) to separate the tokens. See the TIO link.
1. I pushes the loop counter, which is some large unknown number when outside a loop. Divide it by itself to get 1. I use bit-shifting with lshift and OR.
1. Push k, another loop counter, a bunch of times, then get the stack depth. This uses form feeds (ASCII 12) to separate the tokens. Select the line to see there are actually characters there. Using shift + arrow keys while having the line selected will show that there is an invisible character after each k.

I can lower the byte count by using more unique bytes (like *), but for the moment I'm going to use as few unique bytes as possible.

• Can you use something like variable v v @ v @ = negate for 1, freeing 1 up for 11? – Neil Jun 7 '17 at 10:05
• @Neil I found some better options. I don't know if there are enough whitespace characters left to use as token separators. – mbomb007 Jun 7 '17 at 16:54
• Great! I like to think I got you thinking anyway, even if you didn't use my specific suggestion. – Neil Jun 7 '17 at 19:51
• @Neil I did use it in an older revision, but it wasn't long before I changed to using I I /. – mbomb007 Jun 7 '17 at 21:48

# dc, score 20, 102 bytes

I'm assuming since functions/snippets count and returned values count that leaving the value on the stack counts. Otherwise, since dc has no implicit print and four distinct print commands, the max would be 4. We'll expect a clear stack for each of these, though I guess it only matters for one. Several of these will pollute the stack; top of stack is the value.

1 and 3-9 should be obvious. Likewise A-F work for 10-15 regardless of input base. 50 is the code point for ASCII 2, so for 2 we add our output base (10) to itself until we get up to 50 and convert it with a. For 16, we do (2^2)^2. For 17, we use 17 Ks to put the default precision (0, but this number is irrelevant) on the stack and then count the stack depth (z). For 18, we use X to count the fractional digits in .000000000000000000. 19 is a string made up of 19 commas, and then Z returns the length of a string. Finally we do 20 by using I to get our input base (10), and essentially doing (10-10)-(((10-10)-10)-10) or 0-_20.

Try it online!

A lot of this is made easier by the fact that Perl 6 supports numbers being represented by Unicode. This allows us to do things like substituting the digits of 14 for the technically equivalent digits ۱۴, as long as we don't have byte conflicts in the multi-byte characters.The tradeoff is that all the bitwise operators have to be prefixed by +, which narrows down what we can do.

## Explanation:

### 1

!@/!@


Divide the logical not of two anonymous empty state variables to get 1

### 2

τ÷π


Divide tau by pi. Since tau is 2*pi, this equals 2.

### 3

³


The unicode character SUPERSCRIPT THREE, which evaluates to 3 when not after another number.

### 4

4


Just a plain ol' 4.

### 5

^?'~'~^''


The unary ? operator coerces '~' to a string, which is then converted to the range [0,1) by ^ and then coerced to the string 0 before being XOR'ed with '' (5) and converted back to a string.

### 6 through 9

All of these are normal ASCII characters

### 10

𐭜


This is the character meaning 10 in Inscriptional Parthian.

### 11

11


Two 1s concatenated together.

### 12

[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]


Coercing a list to an int results in the length of the list. +[] == 0 and then +[+[]] == 1. This then adds them together to result in 12

### 13

"{3%%3%3}3"


Checks if 3 is divisible by 3, then mods that with 3 to coerce the True to a 1 and concatenates it with another 3.

### 14

Int((),(),(),(),(),(),(),(),(),(),(),(),(),())


Same as number 12, where coercing a list to an int results in the length of the list.

### 15

0xF


A hexadecimal literal for 15.

### 16

৹


BENGALI CURRENCY DENOMINATOR SIXTEEN.

### 17

ᛮ


RUNIC ARLAUG SYMBOL. Interesting note, this is actually a numeric letter, as opposed to the numeric digits and numeric other I've used so far.

### 18

⒅


PARENTHESIZED NUMBER EIGHTEEN. Actually recognisable as a number for once.

### 19

꘡꘩


VAI DIGIT's ONE and NINE, making 19.

### 20

-   --$_- --$_-   --$_- --$_-   --$_-$_


Some arithemetic on the topic variable, which is initially set to Nil. These are separated by tabs. This evaluates to 20. (Note that I could save the character _ here, but make it a lot longer)

### 21

Q<Q<CiRCLED NUMBER TWENTY ONE>.UNiPARSE>.lc.EVAL.EVAL


I'm quite proud of this one. The uniparse function can take a string and find the unicode character called that, which is neat. However, it conflicts with our earlier calls to Int (or the alternatives Rat or Numeric). So we wrap it in a string and set the whole thing to lowercase before evaling it. We don't need a single digit number, so we get an appropriate Unicode character and eval it again which yields the 21.

I could have also used the \c[] construct in a string, but I'm using the []s elsewhere.

### 22

22


An integer literal

### 23

٢٣


ARABIC-INDIC DIGITs TWO and THREE making 23.

### 24

㉔


CIRCLED NUMBER TWENTY FOUR

### 25

5*5


Simple multiplication.

### 26

۲۶


ARABIC-INDIC DIGITs TWO and SIX. What do you mean I've already used these? No-no, these are the EXTENDED versions see? Completely different (at least, byte-wise).

### 27

２７

FULLWIDTH DIGIT's TWO and SEVEN

### 28

߂߈


NKO DIGIT's TWO and EIGHT

### 29

ord
q


Return the value of the byte, which is 29. The function doesn't care about the type of whitespace, so I've used a newline here.

## Possible further improvements

I can still use various whitespace characters to separate function from argument, but I can't find any that result in a number and don't conflict with all the letters I've already used (e.g. chars, codes, index, encode.bytes).

I've also used up pretty much all the usable non-conflicting bytes between numeric Unicode characters that Perl 6 recognises.

If I could figure out how to get the code for 5 (^?'~'~^'') to do multiple digit numbers, I could free up * for something. I also have enough characters to declare a variable, though I don't know what I'd do with it.

• @ØrjanJohansen I guess I could changr to a different encoding and post all the bytes individually for each unicode character? It wouldn't change much and make parts of it unreadable... – Jo King Jul 6 '18 at 3:52

All are snippets except for 16, which is a full program. Some control characters are present, I've written them in the form \x?? here.

## Explanations

1. !

Pop an implicit zero off the empty stack and perform a logical negation to get 1.

2. - 15.

Numeric literals

16. y\-.@

Full program. y is the "Get SysInfo" instruction. The first number dictates whether or not some of the Befunge-98 features have been implemented (details) - by default in PyFunge this is 15. The second number is the cell size in bytes, for which PyFunge returns -1, as it uses arbitrary precision integers. Swapping those numbers and subtracting them gives 16. .@ = output as number then exit.

17. 11111111111111111++++++++++++++++

A mysterious one.

18. '\x12

Pushes the code of character 18 onto the stack.

19. "\x13"

Pushes the string onto the stack. Strings actually get pushed backwards - do not be alarmed!

20. 0gg0g###########################\x14

g gets a character code by coordinates. The first g gets the character at (0, 0), which is 48, the next gets the character at (0, 48), which is 32 (by default, the plane is filled with spaces), and the third gets the character at (32, 0), which is the control character 20.

## Unused characters

These are the remaining instructions, none of which appear very useful for creating numbers:

Obtains 2 via matrix multiplication of Booleans. For 6, we use the gamma (Γ) function (gamma(n) == factorial(n-1)). For 10, 0xA has to be |-ed with 0 since we want the output in decimal notation, not hexadecimal.

I wrote it for Julia 0.7, but it works in Julia 0.6 too without a hitch.

Let me know if there are ways to go beyond 13 (or if I've made some mistake by repeating a character anywhere here).

# Chip, score 1

t*ae*f


Yep, only 1.

The above code (plus at least one of the flags -w, -z, or -o) outputs the value 0x31, which is the ascii code point for the digit '1', then terminates itself:

t        If active, terminate execution after printing the current output byte
*       Activate neighboring elements
a      If active, set output bit 0x01 to 1
e     If active, set output bit 0x10 to 1
*    Activate neighboring elements
f   If active, set output bit 0x20 to 1


Since e and f are required in order to output every digit (as they are the only way to set those bits), we can't go any higher than a single digit.

# Fission 2, Score: 2, 10 bytes

1: R'1!;

2: *"2"L


Try it online!

As far as I know, this is as high as you can possibly get in Fission, as the program has to start at one of RLUD characters, and you have to use " or ! to output

In hindsight this can probably be improved by taking advantage of Snippets are allowed!

### Explanation

1:

R'1!;
R       Spawn atom with 1 mass, 0 energy, moving right
'1     Set atom's mass to ASCII value of 1
!    Print character represented by atom's mass
;   Destroy atom


2:

*"2"L
L   Spawn atom with 1 mass, 0 energy, moving left
"    Enter printing mode, print all chars atom moves over
2     Print 2
"      End printing mode
*       Terminate program


# ><>, Score 2, 8 Total Bytes

Can't go any higher, there are only 2 output commands: n for numbers, and o for characters.

1n;


Prints 1, as a number.

'2'ov


Pushes 2's ascii value to the stack. Prints it as a character. Loops forever, since there's no way to end the program without re-using a semicolon.

• There's a ><> answer already, which does a lot better since answers can be "snippets". – Ørjan Johansen Nov 18 '17 at 18:56
• Ah, I see. Oh well ¯_(ツ)_/¯ – Bolce Bussiere Nov 18 '17 at 19:30
• Also, you can end the program using any non-instruction, dividing by 0 or doing any instruction without a sufficient amount of items in the stack – Jo King Dec 30 '17 at 12:41

## (K+R)eg, score 32

Our task is to write as many programs / functions / snippets as you can, where each one outputs / prints / returns an integer. The integer is already on the stack, so it should have already returned the integer. The method of outputting does not matter.

• 1-9 implicit outputs the respective integer. We are using control characters for this. In order to save the 1 character, we should do \x03\x02> instead.
• 10(TIO):
\


• 11-31 Yes, you need control characters! In order to return a specified number, you only need to convert the integer to its ASCII character form. Unfortunately this is in the ASCII range, and implicit integer output does not work.

Returning 13 is a special case(TIO):

;

• 32 Great, so this is automatically pushed onto the stack.

So I can't think of more methods.

• Couldn't you push 33 to the stack by pushing 2 Unicode characters that have a difference of 33, then subtracting? – EdgyNerd Sep 14 at 16:00
