Print combinations of alphabets in a sequence
Hi Friends,

I have a series of alphabets like this

Code:
[CA]A[GCAT][ATG][AA]GCAA[TG]

The values inside the square brace indicate that either of them can be present at that position. And those ones without a brace, means that they are the only ones that could be printed at that location.

Now, I would like to know if there is a possibility for a script to print all possible combinations of these alphabet occurrences.

For an example sake, if I consider only the first alphabet within a square brace, the output would be

Code:
CAGAAGCAAT

The alphabets in bold indicate the first ones in the square brace. Like this way, is there a possibility to print all possible combinations?

Thanks

ppi::statement::unmatchedbrace

PPI::Statement::UnmatchedBrace(3)			User Contributed Perl Documentation			 PPI::Statement::UnmatchedBrace(3)

NAME

       PPI::Statement::UnmatchedBrace - Isolated unmatched brace

SYNOPSIS

	 sub foo {
	     1;
	 }

	 } # <--- This is an unmatched brace

INHERITANCE

	 PPI::Statement::UnmatchedBrace
	 isa PPI::Statement
	     isa PPI::Node
		 isa PPI::Element

DESCRIPTION

       The "PPI::Statement::UnmatchedBrace" class is a miscellaneous utility class. Objects of this type should be rare, or not exist at all in
       normal valid PPI::Document objects.

       It can be either a round ')', square ']' or curly '}' brace, this class does not distinguish. Objects of this type are only allocated at a
       structural level, not a lexical level (as they are lexically invalid anyway).

       The presence of a "PPI::Statement::UnmatchedBrace" indicated a broken or invalid document. Or maybe a bug in PPI, but far more likely a
       broken Document. :)

METHODS

       "PPI::Statement::UnmatchedBrace" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element.

SUPPORT

       See the support section in the main module.
