import java.util.*;

public class Main {
	public static void main(String args[]){
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		int a = n / 100;
		int b = (n % 100) / 10;
		int c = n % 10;
		if(a == 1) {
			a = 9;
		} else if(a == 9){
			a = 1;
		}
		if(b == 1) {
			b = 9;
		} else if(b == 9){
			b = 1;
		}
		if(c == 1) {
			c = 9;
		} else if(c == 9){
			c = 1;
		}
		
		System.out.println(a * 100 + b * 10 + c);
	}
