/* Java */

Scanner x = new Scanner(System.in);
int a, b, c;
a = x.nextInt();
b = x.nextInt();
c = x.nextInt();

if(a<b && a<c)
if(b<c) System.out.print(a+""+b+""+c);
else System.out.print(a+""+c+""+b);
if(b<a && b<c)
if(a<c) System.out.print(b+""+a+""+c);
else System.out.print(b+""+c+""+a);
if(c<a && c<b)
if(a<b) System.out.print(c+""+a+""+b);
else System.out.print(c+""+b+""+a);
