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: Accepted)

# include <stdio.h>

int main(){
    int n;
    scanf("%d", &n);

    if (n == 999)
        printf("%d", 111);
    else if (n == 991)
        printf("%d", 119);
    else if (n == 919)
        printf("%d", 191);
    else if (n == 199)
        printf("%d", 911);
    else if (n == 911)
        printf("%d", 199);
    else if (n == 191)
        printf("%d", 919);
    else if (n == 119)
        printf("%d", 991);
    else
        printf("%d", 999);    


    return 0;
