Problem Statement

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 f(int x){
    x==9 ? (x=1):(x=9);
    return x;
}

int main(void){
    // Your code here!
    int a,b,c,d;
    scanf("%d\n",&a);
    b=a/100;
    d=a%10;
    c=a-b*100-d;
    printf("%d\n",f(b)*100+f(c)*10+f(d));
}
