#include <stdio.h>
int main(){
  
    int i;
    int a[3];
  
    for(i = 0; i < 3; ++i){
        scanf("%d", &a[i]);
          if(a[i] = 1){
            a[i] = 9;
          }
          else {
            a[i] = 1;
          }
    }
  
    printf("%d\n", a[1] * 100 + a[2] * 10 + a[3]);
  
return 0;
