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: Wrong Answer)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
	public static void main(String[] args) {

		try {
			InputStreamReader isr = new InputStreamReader(System.in);
			BufferedReader br = new BufferedReader(isr);
			String buf = br.readLine();
			int n = Integer.parseInt(buf);
			int i = 1;
			do{
			//CHECK_NUM:
				int x = i;
				//System.out.print(" x:"+x+" ");
				if( x % 3 == 0 ){
					System.out.print(" "+i);

			//INCLUDE3:
				}else if( x % 10 == 3 ){
					System.out.print(" "+i);
				}else {
					x/=10;
					for(;x % 10==3;){
						System.out.print(" "+i);
						break;
					}
				}
			//END_CHECK_NUM
				if(++i >= n){
					System.out.println(" "+i);
					break;
				}
			}while(true);

		} catch (IOException e) {
			System.err.println(e);
		}
	}

}
