Hello,
Could I get a hint on the error message of my solution for PALIN using sbcl? I have tried several different things but always NZEC and I am running out of ideas.
I have made my program recognize inputs with and without spaces after the digits (and before every newline) because some comments said I should. I also think I handle EOF correctly.
It would be useful to know if my program prints out some results or none at all.
