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.util.Scanner;

public class Main {

	private static int i = 1;
	private static int n;

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		n = sc.nextInt();
		check_Num();
		System.out.println();
		sc.close();
	}

	private static void check_Num() {
		if (i % 3 == 0) {
			System.out.print(" " + i);
			end_Check_Num();
		} else {
			include3();
		}
	}

	private static void include3() {
		String value = String.valueOf(i);
		for (int index = value.length(); index > 0; index--) {
			if (i / (int) Math.pow(10, index - 1) % 10 == 3) {
				System.out.print(" " + i);
			}
		}
		end_Check_Num();
	}

	private static void end_Check_Num() {
		i++;
		if (i <= n) {
			check_Num();
		}
	}
}
