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

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

#include<stdio.h>
int replace(  int number)
{

if (number == 0)
return 0;


int digit = number % 10;
if (digit == 1)
digit = 9;
else if (digit == 9)
digit = 1;



return replace(number/10) * 10 + digit;
}
int Convert(  int number)
{
if (number == 0)
return 1;
else
return replace(number);
}
int main()
{
  int number;
scanf("%d", &number);
printf("%d\n", Convert(number));
return 0;
}
