Given an integer number n (0<=n<10000), write a code returning the difference between the product of its digits and the sum of its digits. For instance, if n=432 then the result is 4*3*2-(4+3+2) = 15.

% check this
a = 4321;
b=str2num(num2str(a)');
diff = abs(sum(b)- prod(b))

That code seems to work when I test, except for 0 exactly.
For 0 exactly your Y would be 1 and your X would be 0 so you would get 1-0 = 1 as your solution, but for 0 exactly the product of the digits should be 0.
