Random Integer to EnglishIn this code golf exercise, you must generate a uniform random integer from 1 to 10,000. You should then output each integer in that random number in English separated by spaces.
Example:
Random Number:
4603
Output:
four six zero three
You must try to achieve this in the smallest amount of characters possible in a language of your choice.
Please format your solution as the language name followed by the number of characters that your solution contains before writing out the solution in a code block.
Good luck!
This is a replacement for "Convert the integers" so that it can be fair for all users to attempt. |

I'll start us off with an easy one, just the first way I thought to do it shortened.
Lua, 167 characters.
a,b={"zero";"one";"two";"three";"four";"five";"six";"seven";"eight";"nine"},''for d in tostring(math.random(1,10^4)):gmatch"."do b=b..a[tonumber(d)+1].." "end print(b)

Looks good, 128Gigabytes! We'll have to see if anyone can come up with a shorter solution! |

Lua, 161 characters.
print(({tostring(math.random(1, 10^4)):gsub(".", function(c) return ({"zero";"one";"two";"three";"four";"five";"six";"seven";"eight";"nine"})[c+1]..' 'end)})[1])
Or this, if it is okay to have it also print an extra number at the end (Since gsub returns 2 values.)
Lua, 154 characters.
print(tostring(math.random(1, 10^4)):gsub(".", function(c) return ({"zero";"one";"two";"three";"four";"five";"six";"seven";"eight";"nine"})[c+1]..' 'end))

math.randomseed(tick())
local a={"zero","one","two","three","four","five","six","seven","eight","nine"}
local r=tostring(math.random(1,10^4))
local c=""
for i=1,#r do
c=c.." "..a[tonumber(r:sub(i,i))+1]
end
print(c)
In terms of shortness, I lost. I just like keeping my code clean, organized, and readable. Sorry.  |

I think I've the smallest solution so far here:
import random
d=("zero","one","two","three","four","five","six","seven","eight","nine")
for c in str(random.randint(1,1e4)):
print(d[int(c)])Written in python with 142 characters.

vha's 142 char solution forced me to look for ways to shorten my first-off solution that was 149 chars, and thus I'm only ousting him by 1 char! Awesome solution, vha.
JavaScript* ,141 characters
(Math.floor(Math.random()*9999+1)+'').split('').map((d)=>{return ['zero','one','two','three','four','five','six','seven','eight','nine'][d]})
Shortcuts used:
+'' to typecast string vs String() and .toString()
()=> anonymous function shorthand in ECMA6
string:number array reference behavior (See ["zero", "one", "two"]["1"] : one)
* ECMAScript 2015 / modern web console

Thanks Josh! Apologies for missing formatting specification on the first go around.

warn(s:gsub('.',function(v)return({'zero','one','two','three','four','five','six','seven','eight','nine'})[v+1]..' 'end))
121 characters
Edit: some people didn't include a way of outputting the string itself, so getting rid of the warn call makes this 115 characters.

warn(s:gsub('.',function(v)return({'zero','one','two','three','four','five','six','seven','eight','nine'})[v+1]..' 'end)) 121 characters Specification for this run says "you must generate a uniform random integer from 1 to 10,000", but from what I can tell, you're substituting 's' for this operation. I'm honestly a complete newb at code golf - only been coding for a few years, golfing for about 2 weeks - so if this is a conventional standard that has made it over from some other communities that can be automatically assumed while golfing, I'd be very curious to know more. My problem with it is that such a convention would give a ton of task interpretation to the individual golfers themselves. Someone used 's' to skip an entire chunk of the Golf Course, so why not use 's' to skip even more? This could eventually devolve until solutions to potentially "open" courses are some version of the following: print(s) |
