The following puzzle was quite amusing for (prep?) us this afternoon:

	For a string containing quoting backslashes, compute
	the boolean vector that marks all those backslashes
	-- but not backslashes that are quoted on their part!

	i.e.:  FUN 'a\*b\\c'  yields: 0 1 0 0 1 0 0
	       FUN 'a\\\*'    yields: 0 1 0 1 0
	
The usual puzzle contraint applies, of course:
Don't use a loop in FUN. Send solutions to:
