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

Sample Output 2

111

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<stdio.h>
int main(void){
  int n, m,l;
  scanf("%d",&n);
  if(n / 100 == 1){
    m += 900;
  }
  else{
    m+= 100;
  }
  n -= m;
  if(n / 10 == 1){
    l += 90;
  }
  else{
    l += 10;
  }
  n -= l;
  if(n == 1){
    printf("%d\n",m+l+9);
  }
  else{
    printf("%d\n",m+l+1);
  }
  
  return 0;
}
