Constraints

111 \leq n \leq 999

n is an integer consisting of digits 1 and 9.

Input

Input is given from Standard Input in the following format:

n

Output

Print the integer obtained by replacing each occurrence of 1 with 9 and each occurrence of 9 with 1 in n.

Sample Input 1

119

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>

int main()
{
	int n,d,m=0,i=1;
	
	scanf("%d",&n);
	
	while(n!=0){
		d=n%10;
		if(d==1){
			m=m+9*i;
		}
		else{
			m=m+1*i;
		}
		n=n/10;
		i=i*10;
	}
	printf("%d\n",m);
	
	return 0;
