Output the missing integerYou must generate a string that contains every integer from 0-9 that is missing one of the integers. Your program should then output the missing integer. Your program must not output anything else i.e. multiple newlines or spaces. The string must be created in your code, you are not allowed to take any input. Hard-coded solutions are not allowed.
Examples:
012346789 -> 5128394507 -> 6
If you do not know where to start, we suggest using the string.match function or the string.find function because it's one character shorter.
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!

Lua, 22 characters (2 spaces, 1 newline)
s = "12346789"
print("5")
You never said anything about the string being randomly generated.

You never said anything about the string being randomly generated. Sorry, I forgot to mention in the post that hard-coded solutions are not allowed. The post has been updated. |

print(45-load(("return 012356789"):gsub("%d","%1".."+"):sub(0,-2))())

local r = math.random(9)
local s = ""
for i = 1,9 do
if i ~= r then
s = s .. tostring(i)
end
end
print(r)

Thanks for attempting to solve the puzzle LittleBigKid! Unfortunately, your solution just outputs the random number given and does the opposite of what is asked for. |

Lua, 285 characters.
local int,found,missing = "012456789",{},{};
for i = 0,9 do found[tostring(i)] = false; end
for i in tostring(int):gmatch("%d") do if not found[i] then found[i] = true; end end
for i,v in next,found do if not v then missing[#missing+1] = i; end end
print(table.concat(missing,", "));

x=0 for z in("012346789"):gmatch("%d")do x=x+z end print(45-x)
Lua, 62 characters.

Thanks for attempting to solve the puzzle LittleBigKid! Unfortunately, your solution just outputs the random number given and does the opposite of what is asked for. Definitely deliberate, and I definitely understand the puzzle |

128 you can nitpick yours a bit more to make it 4 characters shorter but that'd be a lame way for me to win. Trying to think of a new short approach  |

x=0("012346789"):gsub(".",function(z)x=x+z end)print(45-x)
