Challenge 7

Problem
Make a program that, given an input as a string, outputs the (newline-separated) indexes of the string where the letters that make up the word "code" appear (one of each in order). For example, for input such as:

School is about to start! Be sure to do your homework!

the letters that make up the word "code" are marked by asterisks here:

School is about to start! Be sure to do your homework!
 ^ ^                                 ^          ^

(in that exact order) (search should be case-insensitive if possible)
And the output would be:

2
4
38
49

(the positions of the characters in the string).
Simply output ONLY 0 if such is impossible.

If any further clarification is needed, contact me. I will try to search for order. (honestly, nobody comments about the puns anymore )

Nice for a first submission, pimath.

Got a 101-bytes one in Lua.

Also, that's assuming you want to have displayed only 0 if it's not possible, and nothing else printed during the process.
(Because if other number can appear in the loop as well as 0, well, I got a shorter one.)

47 43 42 bytes of Ruby here.

Oh wait, my solution throws an error instead of printing 0. Whatever, that just adds 8 bytes.

If "c" "o" "d" "e" can't be found (in that order) in the string, then print 0 and nothing else.

Anyway, for my Lua solution, wrapped in a function, it's 121 bytes, then.

Oh. Well I'll have to do it again then.

Lately, I've thought o fmakinga Lua "preprocessor" thingy/language that would feature much shorter things but in the end it would be run as Lua.
It might be called GolfLua, who knows (any idea ? )

Set up as a library like BetterLuaAPI but designed for golf? That would be really cool, I might do something similar.
