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: Accepted)

#include<stdio.h>
int main(void)
{
	int n;
	scanf("%d",&n);
	if(n==111){
		printf("999\n");
	}
	else if(n==911){
		printf("199\n");
	}
	else if(n==191){
		printf("919\n");
	}
	else if(n==119){
		printf("991\n");
	}
	else if(n==991){
		printf("119\n");
	}
	else if(n==199){
		printf("911\n");
	}
	else if(n==919){
		printf("191\n");
	}
	else if(n==999){
		printf("111\n");
	}
	return 0;
