Cat Snuke is learning to write characters.
Today, he practiced writing digits 1 and 9, but he did it the other way around.

You are given a three-digit integer n written by Snuke.
Print the integer obtained by replacing each digit 1 with 9 and each digit 9 with 1 in n.

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

Sample Output 1

991

Replace the 9 in the ones place with 1, the 1 in the tens place with 9 and the 1 in the hundreds place with 9. The answer is 991.

Sample Input 2

999

Sample Output 2

111

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int main(void)
{
	int ans[2];
	int s;
	scanf("%d",&s);
	
	ans[0]=s/100;
	ans[1]=s/10;
	ans[2]=s%10;
	
	
	if(ans[0]=1){
		ans[0]=9;
		}else{
			ans[0]=1;
			}
			
	if(ans[1]=1){
		ans[1]=9;
	}else{
		ans[1]=1;
	}
	
	if(ans[2]=1){
		ans[2]=9;
	}else{
		ans[2]=1;
		
	}
	
	printf("%d",ans[0]*100+ans[1]*10+ans[2]);

	return 0;
