Problem: Luke Skywalker gave Chewbacca an integer number x. Chewbacca isn't good at numbers but he loves inverting digits in them. Inverting digit t means replacing it with digit 9 - t. 

Help Chewbacca to transform the initial number x to the minimum possible positive number by inverting some (possibly, zero) digits. The decimal representation of the final number shouldn't start with a zero.

Input

The first line contains a single integer x (1 ≤ x ≤ 1018) — the number that Luke Skywalker gave to Chewbacca.

Output

Print the minimum possible positive number that Chewbacca can obtain after inverting some digits. The number shouldn't contain leading zeroes.

Solution:
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        while(sc.hasNext()) {
            String num = sc.next();
            for (int i = 0; i < num.length(); ++i) {
                if (i == 0) {
                    if ('5' <= num.charAt(0) && num.charAt(0) <= '8')
                        System.out.print((char) ('0' + 9 - num.charAt(0) + '0'));
                    else
                        System.out.print(num.charAt(0));
                } else {
                    if ('5' <= num.charAt(i) && num.charAt(i) <= '9')
                        System.out.print((char) ('0' + 9 - num.charAt(i) + '0'));
                    else
                        System.out.print(num.charAt(i));
                }
            }
        }
