Convert 1, 2, 3, 4, 5, 6, 7, 8, and 9 to "one", "two", "three", etc

Question

Winner: professorfish's bash answer! An entire 9 bytes! Wow!

You may continue to submit your answer, however you can no longer win. Original post kept for posterity:

---

Your goal is to convert a whole number between 1-9 into the word it represents.

• You will not need to worry about decimals
• The user will input a number. Assume that they will never enter anything 10 or higher
• The user must type the number at some point, however the method the program reads it does not matter. It can be with stdin, reading a text file, etc, however the user must press the 9 button on their keyboard (for example) at some point
• It is not case sensitive (ie, "one", "One", "oNe", "OnE", etc are all acceptable)
• HTTP/etc requests are allowed, however any code executed by the server the request is made to counts towards the byte count of your final code (e.g. if I had a C++ program make a HTTP request, the PHP code used in the HTTP request counts)
• Anything that can compile and run is acceptable

Answer 1

Python 2, 64

print' ottffssennwhoiieiieoruvxvgn  ere ehe  e   nt'[input()::9]

This is what the string looks like with some extra whitespace (try reading vertically):

o t t f f s s e n
n w h o i i e i i
e o r u v x v g n
    e r e   e h e 
    e       n t

As explained in the comments below, [input()::9] starts at the given index and selects every ninth subsequent character.

Answer 2

Bash (with bsdgames), 9

number -l

Reads from standard input.

I don't know why there's a utility for this, but whatever.

Answer 3

Common Lisp - 22 bytes

Here's a general one (not just for one-ten):

(format nil"~R"(read))

Oh, you want ordinals (first, second, ... three-hundredth...)? Ok!

(format nil"~:R"(read))

Answer 4

BASH 51

So I made another one using my second idea plus some help from others:

set one two three four five six seven eight nine

$X

Where 'X' is the number you want.

---

BASH 48 (67)

67 with \n line breaks

I'm not sure if this totally counts, because it's reading from a file, but:

sed -n Xp a

Where "X" is the input and where a is a file with:

one
two
three
four
five
six
seven
eight
nine

The file is 36 chars, and the bash command is 13.

How it works:

Each line in the file is numbered, starting with 1. So 'one' is on the 1st line, 'two' on the 2nd. The command, sed -n 'Xp' a says, "Please print what's listed on line 'X' of file 'a'" sed is a Unix stream editor. -n means be silent, or only essentially ignore everything else. Xp means print what's on line 'X'.

Answer 5

C# - 127 ( 86 / 46)

If you only take the executable part...

Console.Write(((HourOfDay)Console.Read()-48));

and if HourOfDay would have been part of the the System namespace you would need 46 chars. Unfortunately it sits in System.DirectoryServices.ActiveDirectory which makes it 86...the other noise spoils it.

This is compileable and runnable from the commandline (127 chars):

using System;class P{static void Main(){Console.Write((System.DirectoryServices.ActiveDirectory.HourOfDay)Console.Read()-48);}}

if saved to a file called cg2.cs

csc cg2.cs /r:System.DirectoryServices.dll  && cg2

How does this work?

HourOfDay is an enum type so we can use names instead of magic constants. Enum types have a ToString() implementation that gives you the name of the value. You can cast an int to an enum. Console.Read() reads a character from the input stream represented as an integer. typing '1' gives 49, substract 48 to get 1, cast/box to HourOfDay to return 'One'.

Take a look at the Powershell version of this same trick

Atob / btoa can be a poor's man compressing tool (but if you want to try this in console, you cannot copy from the formatted text you see at once. Go to 'edit' and copy from the source panel)

Markdown editor does not like some of the characters in this answer: some characters get lost at saving. Still, I think it's an editor problem, not mine. The lost characters are perfectly valid 8 bit unicode chars.
(Or else I'm wrong, if this issue was already debated in meta, let me know) Here is the version with offending characters escaped, each sequence \xNN should count 1

alert(btoa("×C§{Dð£Dá­ç´\x16\x8b«ÐX¯{D¢ÇD\x9e½éô\x12(!·Cb\x9dí").split(0)[prompt()])

Answer 9

Perl, 55

$_=(nine,eight,seven,six,five,four,three,two,one)[-$_]

It is run with option -p (+1 byte), e.g.:

perl -pe '$_=(nine,eight,seven,six,five,four,three,two,one)[-$_]'

Input is expected in STDIN and output is written to STDOUT.

The code just generates an array and selects the right element. Option -p takes care of reading the input line into $_ and prints the result in $_.

Variations:

• With trailing new line (+3):

  $_=(nine,eight,seven,six,five,four,three,two,one)[-$_].$/
  

  or (same byte count):

  s/./(nine,eight,seven,six,five,four,three,two,one)[-$&]/e
  

Update:

• Using bare words instead of qw[...] (thanks Zaid).

• Negative index saves a byte (thanks aragaer).

Answer 10

Oracle SQL - 46

select to_char(to_date(&1,'j'),'jsp')from dual

Demonstration

This does include a standard loophole, I admit, but the SQL is shorter than Golfscript; I couldn't resist!

It works by (ab)using Oracle's datetime format models. TO_DATE(n, 'j') converts a number into a Julian day, the number of days since January 1, 4712 BC. TO_CHAR(<date>, 'jsp') converts this back into the integer (though as a string). The sp, is a format element suffix that spells the number. This'll actually work with quite a lot of numbers.

The &1 is a substitution variable that'll only work with clients that accept it, for instance SQL*Plus.

bash say (OS X): 3 8

"Your goal is to convert a whole number between 1-9 into the word it represents"

Last time I checked, spoken words are words as well. Previous attempt (accepts no input)

Type any number and the word comes out. I know the end date is due, but in my opinion I should have won the contest.

Answer 14

Perl, 60 bytes

$_=(ZOneTwoThreeFourFiveSixSevenEightNine=~/.[a-z]*/g)[$_]

Requires the -p switch (two bytes).

Example

$ perl -p convert.pl <<< 5
Five

How it works

• -p reads from STDIN and saves the result in $_.

• =~/.[a-z]*/g splits the preceding bareword into substrings of one (uppercase) letter followed by any number of lowercase letters.

• (…) collects the substrings into an array.

• [$_] retrieves the substring corresponding to the user input.

• $_=… saves the result in $_.

• -p prints the value of $_.

Answer 15

Bash + coreutils, 64

Non-competitive compression concept

xxd -p<<<TàPnàõ:àsÀ~®@ãCN|tr 0-9a-d \\ng-inor-x|sed -n $1p

Some of the exotic characters here may not render well, so this script may be reconstructed from its base64 representation:

base64 -d <<< eHhkIC1wPDw8VOCLUIJu4PWWDzrgc8B+rkDjEoBDTnx0ciAwLTlhLWQgXFxuZy1pbm9yLXh8c2VkIC1uICQxcA==

Example output

$ ./n.sh 1
one
$ ./n.sh 9
nine
$ 

Explanation

It occurred to me that the string one two three four five six seven eight nine contains only the letters efghinorstuvwx and a space separator - 15 character values in total. Thus each character can potentially be represented in 4 bits, or 2 characters per 1 byte. We can use the hex representation of a byte as an easy way to split each byte into two hex digits. We can then transform the hex digits back to the letters we require using tr or similar. As luck would have it, rstuvwx are consecutive, so may be expressed as r-x to tr. The encoding is arranged such that e and f are left as-is, and that the words are line-break separated, so we can use sed to ouptut just the line we need.

This decoding process ends up using a fair amount of extra space, so makes this answer non-competitive as a shell-script-style answer, but may be a useful concept in other languages.

Answer 16

Python 2.x - 65 64

Not as good as @grc 's answer, but certainly more legible :-)

'one two three four five six seven eight nine'.split()[input()-1]

One less char, thanks to @flornquake

'nine eight seven six five four three two one'.split()[-input()]

Answer 17

DOS Batch - 162 Chars (incl' line breaks)

This answer was inspired by @grc's Python answer, although I did have something similar in mind.

@setlocal enabledelayedexpansion
@set s="ottffssennwhoiieiieoruvxvgn  ere ehe  e   nt
@set /a c=%1
@set z=!s:~%c%,1!
@if _%z%==_ exit /b
@echo %z%
@%0 %c%+9

Usage:

[Filename] [number]

For example, if the code is in a file called speak.bat, and you want to see the number "five", you would run it as:

speak 5

Also, the output is top-to-bottom, not left-to-right! So instead of

five

you will see

f
i
v
e

Answer 18

(pure) Bash, 64

Takes input as its first argument, assuming valid input.

v=(o one two three four five six seven eight nine)
echo ${v[$1]}

Creates an array v, then accesses the element specified on the input. Since arrays are zero-indexed, I had to add a 0th element as a placeholder. Alternatively (thnx @DennisWilliamson for pointing this out):

v=(one two three four five six seven eight nine)
echo ${v[$1-1]}

Answer 19

Perl 36 (58 standalone)

Answer 24

In AppleScript ; 123 chars.

{"one","two","three","four","five","six","seven","eight","nine"}'s item((display dialog""default answer"")'s text returned)

This script takes the input in a dialog. Then it gives the output in AppleScript’s result.

Example :

• Input : 6
• Output : "six"

Here is a nicer version :

set l to {"one","two","three","four","five","six","seven","eight","nine"}
set n to text returned of (display dialog "?" default answer "")
display dialog (l's item n) buttons ("OK") default button 1

This version displays the output in a nice dialog.

Example :

• Input : 9
• Output : nine

[ Answer edited ; slightly improved the dialog for the input ; still 124 chars. Answer edited again ; now 1 char less ! ]

Answer 26

Powershell - 91 74

[Enum]::ToObject([System.DirectoryServices.ActiveDirectory.HourOfDay],[Console]::Read()-48)

Found out how to cast to remove the Enum and ToObject call:

[System.DirectoryServices.ActiveDirectory.HourOfDay]([Console]::Read()-48)

How does this work?

HourOfDay is an enum type so we can use names instead of magic constants. Enum types have a ToString() implementation that gives you the name of the constant value. You can cast an int to an enum. Console.Read() reads a character from the input stream represented as an integer. typing '1' gives 49, substract 48 to get 1, cast to HourOfDay to return 'One'.

Because powershell does a ToString on all objects being written to the output stream and doesn't need the fluff to turn this into an executable this all that is needed besides powershell...

Answer 27

CJam - 50

This is a plain ASCII solution that uses HTTP requests (this is allowed in the question):

"aj21.com/"r+g

On the server there are 9 plain-text files named 1, 2, ..., 9, each containing the corresponding word.

Total size: 14 + 3 ("one") + 3 ("two") + 5 + 4 + 4 + 3 + 5 + 5 + 4 = 50.
It can be golfed more by using a shorter domain.

The online interpreter doesn't support HTTP requests, so the program needs to be run using the java interpreter.
