Online Titel Case Converter

I want to build a list containing every possible permutation of capitalization of a word. so it would be

List<string> permutate(string word){    List<string> ret = new List<string>();    MAGIC HAPPENS HERE    return ret;}

So say I put in "happy" I should get an array back of

{happy, Happy, hAppy, HAppy, haPpy, HaPpy ... haPPY, HaPPY, hAPPY, HAPPY}

I know of plenty of functions that will capitalize the first letter but how do I do any arbitrary letter in the word?

Is there a simple way to convert a string to title case? E.g. john smith becomes John Smith. I'm not looking for something complicated like John Resig's solution, just (hopefully) some kind of one- or two-liner.

I have a String description that holds my sentence. I only want to capitalize the first letter. I tried different things but most of them give me exceptions and errors. Im using Xcode 6.

Here is what I tried so far

let cap = [description.substringToIndex(advance(0,1))] as String    description = cap.uppercaseString + description.substringFromIndex(1)

It gives me: Type 'String.Index' does not conform to protocol 'IntegerLiteralConvertible'

I tried

 func capitalizedStringWithLocale(locale:0) -> String

But I just can't figure out how to make it work. Any ideas?

How do I make the first letter of a string uppercase, but not change the case of any of the other letters?

For example:

• "this is a test" -> "This is a test"
• "the Eiffel Tower" -> "The Eiffel Tower"
• "/index.html" -> "/index.html"

I am trying to update records that have both initcap and upper case letters. For example : Stages Home Health LLC; Dana Ash

It has both Initcap "Stages" and Upper which is "LLC"

I have tried using and with a where clause, but have not gotten the result needed

select bbl_id, entity_name from bbl_dq_test where entity_name =

UPPER (ENTITY_NAME) AND ENTITY_NAME = INITCAP (ENTITY_NAME);

but I am looking for something that resembles

update bbl_dq_test Aset Text_field_format = 'BOTH'where entity_name = ( A clause that finds Initcap and Upper together)

select bbl_id, entity_name from bbl_dq_test where entity_name =

UPPER (ENTITY_NAME) AND ENTITY_NAME = INITCAP (ENTITY_NAME);

Only returns numbers.
