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 input, output;
    int data[3];
    int i;

    // 数字の入力
    scanf("%d", &input);
    
    data[2] = input / 100;
    data[1] = (input - (100 * data[2])) / 10;
    data[0] = input - (100 * data[2]) - (10 * data[1]);
    
    for(i = 0; i < 3; i++)
    {
        if( data[i] == 1)
        {
            data[i] = 9;
        }
        else if( data[i] == 9 )
        {
            data[i] = 1;
        }
    }
    
    output = (100 * data[2]) + (10 * data[1]) + data[0];
    
    // 出力
    printf("%d\n",output);
    return 0;
