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.

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>
int main(void){
  int i,j;
  scanf("%d",&i);
  if (i%10==9){
    i-=8;
  }else if (i%10==1){
    i+=8; 
  }
  j=i/100;
  if (j==9){
    i-=800;
  }else if (j==1){
    i+=800; 
  }
  j=(i/10)%10;
  if (j==9){
    i-=80;
  }else if(j==1){
    i+=80;
  }
  printf("%d",i);
  return 0;
}
