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.

import java.util.*;
class Main
{
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int n=sc.nextInt();
		StringBuffer sb = new StringBuffer();
		for(int i=n;i<=999;i++)
		{
			if(check(i))
			{
				System.out.println(i);
				break;
			}

		}
	}

	static boolean check(int n)
	{
		int x=n%10;
		n/=10;
		if(n%10!=x)
			return false;
		n/=10;
		if(n%10!=x)
