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 9.2.1) (judge verdict: Accepted)

#include<stdio.h>

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

   int a = n / 100;
   int b = (n / 10) % 10;
   int c = (n % 10) % 10;

   if(a == 1) {
      a = 9;
   } else if(a == 9) {
      a = 1;
   }

   if(b == 1) {
      b = 9;
   } else if(b == 9) {
      b = 1;
   }

   if(c == 1) {
      c = 9;
   } else if(c == 9) {
      c = 1;
   }

   printf("%d%d%d\n", a,b,c);
   
   return 0;
}
