Problem:
Structured Programming

In programming languages like C/C++, a goto statement provides an unconditional jump from the "goto" to a labeled statement. For example, a statement "goto CHECK_NUM;" is executed, control of the program jumps to CHECK_NUM. Using these constructs, you can implement, for example, loops.

Note that use of goto statement is highly discouraged, because it is difficult to trace the control flow of a program which includes goto.

Write a program which does precisely the same thing as the following program (this example is wrtten in C++). Let's try to write the program without goto statements.

void call(int n){
int i = 1;
CHECK_NUM:
int x = i;
if ( x % 3 == 0 ){
cout << " " << i;
goto END_CHECK_NUM;
}
INCLUDE3:
if ( x % 10 == 3 ){
cout << " " << i;
goto END_CHECK_NUM;
}
x /= 10;
if ( x ) goto INCLUDE3;
END_CHECK_NUM:
if ( ++i <= n ) goto CHECK_NUM;

cout << endl;
}

Input

An integer n is given in a line.

Output

Print the output result of the above program for given integer n.

Constraints

3 ≤ n ≤ 10000

Sample Input

30

Sample Output

3 6 9 12 13 15 18 21 23 24 27 30

Put a single space character before each element.

Solution in JAVA (judge verdict: WA: Presentation Error)

import java.io.*;
public class Main{
	public static void main(String[] args){
		BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
		String line;
		int n = -1;
		int i = 1;
		int x;
		try{
			line = reader.readLine();
			n = Integer.parseInt(line);
			while(true){
				x = i;
				if(x % 3 == 0){
					System.out.print(" "+i);
				}else{
					while(true){
						if(x % 10 == 3){
							System.out.print(" "+i);
							break;
						}else{
							x /= 10;
							if(x != 0){
								continue;
							}else{
								break;
							}
						}
					}
				}
				if(++i <= n){
					continue;
				}else{
					break;
				}
			}
			
		}catch(IOException e){
			System.out.println(e);
		}
		
	}
