## CJam (<strike>25</strike> 24 bytes)

    q~e!{_z=},"True""False"?

[Online demo](http://cjam.aditsu.net/#code=q~e!%7B_z%3D%7D%2C%22True%22%22False%22%3F&input=%5B%22FILE%22%20%22LEAD%22%20%22EDDY%22%20%22ICED%22%5D). Pretty trivial apart from the specified output, because CJam doesn't have a Boolean type.

With thanks to [Sp3000](http://codegolf.stackexchange.com/users/21487/sp3000) for saving one stroke.
