function s=myfun()

flag=0;

i=10;

while(flag==0)

a=num2str(i);

b=num2str(2*i);

c=num2str(3*i);

d=num2str(4*i);

e=num2str(5*i);

f=num2str(6*i);

m=length(a);

if((m==length(b))&&(m==length(c))&&(m==length(d))&&(m==length(e))&&(m==length(f)))

a=order(a);

b=order(b);

c=order(c);

d=order(d);

e=order(e);

f=order(f);

if(strcmp(a,b)&&strcmp(a,c)&&strcmp(a,d)&&strcmp(a,e)&&strcmp(a,f))

flag=1;

s=i

end

end

i=i+1;

end

end

function b=order(a)

m=length(a);

for j=1:m-1

temp=a(j);

for k=j:m

if temp>=a(k)

temp=a(k);

r=k;

end

end

temp=a(j);

a(j)=a(r);

a(r)=temp;

end

b=a;

end
