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

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

#include<stdio.h>

int main()
{

int n;
scanf("%d",&n);
int r;
int a,b,c;
a=n%10;
n=n/10;
b=n%10;
n=n/10;
c=n%10;
//printf("%d %d %d",a,b,c);
if(c==1){
c=9;
printf("%d",c);
}
else{
c=1;
printf("%d",c);
}

if(b==1){
b=9;
printf("%d",b);
}
else{
b=1;
printf("%d",b);
}
if(a==1){
a=9;
printf("%d",a);
}
else{
a=1;
printf("%d",a);
}



return 0;
