Talk:Catalan numbers/Pascal's triangle

extracting Catalan numbers from Pascal's triangle

As I understand this task's requirements, the Catalan numbers are to be extracted from Pascal's triangle (and therefore, not be directly computed via binomial coefficients or some other means).   Should programming solutions that don't extract Catalan numbers from Pascal's triangle be flagged as incorrect? -- Gerard Schildberger (talk) 18:50, 20 October 2014 (UTC)
