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 2

111

Solution in C (GCC 9.2.1) (judge verdict: Accepted)

#include<stdio.h>
int main()
{
	int n;
	int a,b,c;
	scanf("%d",&n);
	a=n%10;
	n=n/10;
	b=n%10;
	n=n/10;
	c=n%10;
	if(a==9){
		a=1;
	}
	else{
		a=9;
	}
	if(b==9){
		b=1;
	}
	else{
		b=9;
	}
	if(c==9){
		c=1;
	}
	else{
		c=9;
	}
	printf("%d\n",c*100+b*10+a);
	return 0;
