it seems look-up table solutions are becoming a bit of an issue, could you please add a few test cases to discourage this? +1 for random test cases that are a bit harder to trick, for example something like n=randi(100,1,randi(10)); expr = "(+" + string(num2str(n))+ ")"; assert(isequal(eval_lisp(expr), sum(n)));
I think another test case with multiple expressions would be equally useful. Even something as simple as (+ 1 (* 2 3) 4) would prevent some of the look-up solutions. Make some of those values random, and it will work even better.
Good problem, and better than 44374. Precedence is clear.
Nice. I was trying to figure out how to use strtok, but couldn't quite come up with it.
Are you sure that your Test Suite works? I had to change all the double quotes to single quotes.
Double-quoted strings are string literals in MATLAB R2017a+. To convert a string to char array, use the "char" function.
Thank you for that hint about the "char", bmtran. Never would have figured out what was wrong with my solution otherwise...
