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: Accepted)

import java.util.InputMismatchException;
import java.util.Scanner;

public class Main{


	public static void main(String[] args){

    	Scanner scan = new Scanner(System.in);

				try{
            int n=scan.nextInt();

            call(n);


				}catch(InputMismatchException e){
					System.out.println("??¨??????:"+e);
				}
        	scan.close();


	}


	public static void call(int n){

		int x;
		for(int i=1;i<n+1;i++){

			if(i%3==0 ||i%10==3){
				System.out.print(" "+i);
			}else if((i/10)>0){
				x=i;
				while(x/10>0){
				x/=10;
				if(x%10==3){
					System.out.print(" "+i);
					break;
				}

				}
			}
			//???????????¶????????????????????????????????????i???10??§???????????¨???
			//i/10>0?????¨???



		}System.out.print('\n');


	}
