%given a number x.calculate the smallest positive number you need to add to your original number so that each digit in your sum will have horizontal symmetry.those numbers are [0 1 3 8]
%example x=27=> output =3 because 27+3=30 (horizontal symmetry)
%my code is success with small number,but with big number it is out of memory,so how could i fix it
function y = symmetry(x)
c=x
for i=1:inf
a=num2str(x);
b=uint64(zeros(1,length(a)));
for j=1:length(a)
b(j)=str2num(a(j));
end
b=b(b~=0);
b=b(b~=1);
b=b(b~=3);
b=b(b~=8);
if isempty(b)==1
break
end
x=x+1;
end
y=x-c
end
%take example of big number is x=34567890

Why 3 should be added to 27 to get 30? How 30 is horizontal symmetric? Question is not clear. Can you give another example?
